A Letter to the Children (Part 15)
© 2025 C. O. Bishop
1st John 5:14-21, Final Notes
14 And this is the confidence that we have in him, that, if we ask any thing according to his will, he heareth us: 15 And if we know that he hear us, whatsoever we ask, we know that we have the petitions that we desired of him.
16 If any man see his brother sin a sin which is not unto death, he shall ask, and he shall give him life for them that sin not unto death. There is a sin unto death: I do not say that he shall pray for it. 17 All unrighteousness is sin: and there is a sin not unto death. 18 We know that whosoever is born of God sinneth not; but he that is begotten of God keepeth himself, and that wicked one toucheth him not. 19 And we know that we are of God, and the whole world lieth in wickedness.
20 And we know that the Son of God is come, and hath given us an understanding, that we may know him that is true, and we are in him that is true, even in his Son Jesus Christ. This is the true God, and eternal life.
21 Little children, keep yourselves from idols. Amen.
Introduction:
To begin with, John wraps up his first epistle with several related comments: He offers Encouragement, Teaching, and Admonishment.
Encouragement in Prayer
Obviously, knowing God hears us is a real source of encouragement. This is because we know we are not just “talking into the void.”
There are several verses about answered prayer, in the book of First John, and we can learn about prayer, here.
Teaching, Regarding Sin, and Judgment, and Righteousness
We see that God calls something a “sin unto death.” We will have to compare the rest of Scripture to understand that concept, but it is there for us to learn. Also, we see a definition of sin, here: one of four such definitions in the New Testament.
Admonishment Regarding the Difference Between the One True God and Idols
Finally, John reiterates the union with Christ that has been conferred upon us. More specifically, that we actually can know Him, and we have been placed into Him.
Furthermore, he reiterates what Jesus said in John 17:3. “This is eternal Life that they may know thee the One True God, and Jesus Christ whom thou hast sent.”
And, finally, in contrast to that One True God, in the Person of Jesus Christ, he admonishes us to avoid everything that is not that “One True God.” He says, “Little Children, keep yourselves from idols!” Amen!
What do We Know About Prayer?
Obviously, Jesus encouraged his disciples to always pray.
Also, Paul told the Thessalonian believers to “pray without ceasing.”
Paul also told Timothy that the believers were to pray for all men everywhere, and especially for the leaders, so that the believers could have peaceful lives. God also says this was a “good and acceptable” thing. He said God “ desires all men to be saved and to come unto the knowledge of the truth.”
Sometimes we say, “Well, prayer is just talking to God!” That is an extremely simplistic view of prayer, but true, if only in the same sense that “talking is just communicating with your voice.”
There is More to Prayer thanThat!
Scripture lists different kinds of prayer. The most common prayer we seem to experience is “supplication,” or “petition:” It means asking God for something, whether for ourselves or for someone else. There is nothing wrong with asking: in fact, Philippians 4:6, 7 commands it, along with the giving of thanks. James 4:2, 3 says that sometimes we don’t have what we need because we did not bother to ask the Lord: But he also says, sometimes we do not receive what we asked for because we had wrong motives in asking.
Confession of our sins and our failings, to the God we serve, is also a type of prayer. And it probably should usually precede the other kinds of prayer, because the psalmist said, in Psalm 66:18, that “If I regard iniquity in my heart, the Lord will not hear me.”
When we Praise God, that is a form of prayer. When we Worship or Adore Him, it is also a form of prayer.
We should make the Giving of Thanks a constant part of our prayers: Paul told the Thessalonian believers (1st Thessalonians 5:18) “In every thing give thanks, for this is the will of God in Christ Jesus concerning you!”
Sometimes I remind myself of the other kinds of prayer, so that I do not always come to God asking for something, but rather bring the confession and worship. I use an acrostic, C.A.S.T.
Confession, Adoration, Supplication, Thanksgiving. He commands us to “Cast” all our cares upon Him because he cares for us. 1st John 5:14, 15 is a final review on Prayer.
What Do We Know About Sin, Judgment, and Righteousness?
in John 16:8, Jesus said, “When He (the Holy Spirit) is come, He shall convict the World of Sin and of Righteousness and of Judgment.”
So, it seems fitting that John discusses those three again, here, near the end of the New Testament. There are several things to notice, and some questions to ask, here:
- The people in verses 16-18 are all believers. John addresses believers, and he refers to the one in sin as a brother.
- All unrighteousness is sin, and there is a sin NOT unto death
- But there is also a sin that IS unto death: What KIND of death?
- If the sin is not a “sin unto death,” what kind of sin is it? And why would we need to pray for that brother to save his life, if it is not a sin unto death anyway?
- Why does John immediately confirm, seemingly, that “real believers don’t sin?” Or does he really say that?
Where Did God Judge Your Sins?
If a person is a genuine believer, where did the Lord judge their sins? And, what portion of their sins did He judge there? (When Jesus died for YOUR sins at the Cross, how many of YOUR sins were still in the future? The answer? All our sins were future, and He judged them All at the Cross.)
Jesus said, (John 5:24) that the moment you believed in Him and His finished work at the Cross, you crossed over from spiritual death into spiritual life! (And it was written in “perfect tense,” which implies that you can’t cross back into that spiritual death. You can’t be “UN-born-again!”
So…what kind of death are we talking about? I can experience a sort of “walking dead:” a separation from fellowship with Jesus, caused by any unconfessed sin that I hang onto, whether anger, lust, or any other sin I am unwilling to confess.
Definitions of Sin
Verse 17 says “all unrighteousness is sin” This is one of four New Testament definitions of sin:
- 1st John 3:4 “…sin is the transgression of the Law.”
- 1st John 5:17 “all unrighteousness is sin.”
- James 4:17 “…to him that knoweth to do good and doeth it not, to him it is sin.”
- Romans 14:23 “…whatsoever is not of faith is sin.”
What is a Sin Not Unto Death?
But v. 17 also says “there is a sin not unto death.” So, it can’t be either of these types of spiritual death. You can’t be lost again, but you DO separate yourself from fellowship every time you choose to sin. Neither of those can fit in this context. That leaves only physical death.
There are sins that call for capital punishment. If a Christian commits such a crime, (and they can do so: We are warned in 1st Peter 4:15 to not be a murderer, etc.) then John says, in such a case, we are not to pray that they escape judgment. Their sins were judged at the Cross, yes: but there are always consequences for sins, in this life.
New Testament Examples
And there are cases in the New Testament where believers were literally “taken home” by God for sins that the world would not have judged, at all: But they were actions which undermined the holiness of God’s work on earth. In Acts chapter 5, we saw Ananias and Sapphira, who were believers, but who lied to God, trying to gain honor before other believers. And God revealed their sin, and took their lives.
In 1st Corinthians chapter 11, we read of people who took lightly the holiness and solemnity of the Lord’s Supper. Paul said many of them had been physically sick, and some had physically died, because of that sin.
In both those cases, God decreed that their sin was “unto death,” and it was physical death, but it was for sins that the world would not even have seen as sin, but about which God does care. God does not “ignore our sin.” He hates sin, but He loves the sinners and died for them. And even among believers, He may say, “You have gone far enough! I am bringing you home!”
What About “Sinning Believers?”
In verse 18, John said, “18 We know that whosoever is born of God sinneth not; but he that is begotten of God keepeth himself, and that wicked one toucheth him not. 19 And we know that we are of God, and the whole world lieth in wickedness.”
Some folk attempt to teach that this means “real Christians never sin!” That teaching is not only contrary to the experience of every born-again believer I have ever known; it is also contrary to the truth of God’s Word. Christians do sin. Every single genuine believer is a saved sinner, trying to live in the reality of their new born-again nature. And we often fail!
A New Testament Example:
Peter was already a believer when he denied Jesus, cursing, and swearing that he never knew Jesus. How do I know? Jesus said so! In several places, actually, but specifically, in John 15:3, Jesus told the eleven (including Peter) that they all were clean, through the Word that Jesus had spoken unto them.
And, in Antioch, long after Peter had received the Holy Spirit, both Barnabas and Peter were caught up in the hypocrisy of the Jews who claimed that they could not eat with the Gentile believers. (Galatians 2:11-14) But, honestly, Why would John tell the believers to confess their sins and be cleansed, in 1st John 1:9, if believers never sin?? The answer is, they do sin!
But a believer should not be comfortable in their sin, nor should they willingly continue in sin. One of the results of genuine saving faith isa true continuing repentance, as we see the sin in our lives and confess it, and desire to completely abandon our old way of life.
We know that the World will continually present us with temptations and traps, attempting to ensnare us and to render us unfruitful in our Christian life. But if you have been born again, then you are literally the offspring of God, and you will desire to be with Him, and to walk with Him and to work with Him. You will desire to see Him at work in your life, and desire to see your new life transformed into His holy, righteous life.
The New Life and its Source
20 And we know that the Son of God is come, and hath given us an understanding, that we may know him that is true, and we are in him that is true, even in his Son Jesus Christ. This is the true God, and eternal life.
21 Little children, keep yourselves from idols. Amen.
Jesus, the Son of God, came, born in human flesh, and provided eternal life through faith in His shed blood at the Cross.
Through Him, every believer begins to learn the reality of the New Life in Christ. We have been placed into Him by the Holy Spirit, and the Holy Spirit has taken up residence in our bodies, as a guarantee that we cannot be lost again. He is the true light of the World, the true life that God offers to the World, and the true God in the Flesh who died for us.
Jesus said, in John 17:3 “And this is eternal life that they may know thee the One True God and Jesus Christ whom Thou hast sent.”
He invites us to know Him on an experiential basis, joining Him in His work, in His Love, and in His Life. This is the invitation of God which has been extended to the World from the beginning.
Avoiding Idols
Anything we allow to distract us from the relationship He has offered, is an idol. We ignore the true source of the Living Water, and we go “drink from a muddy creek,” contaminated by the World, the Flesh, or the Devil.
We can either accept HIS invitation, responding daily by faith, or we can ignore it, and miss out. Those are the choices.
Lord Jesus, we ask that you would shine more and more brightly in each of our lives, through the study of your Written Word, and by the authority of Your Holy Spirit, so that we see that we truly have been called as your ambassadors, to be your hands and feet and voice, here on Earth. Give us the faith to follow You in every way.
