What Does it mean, to “Walk as Children of Light?”

Ephesians 5:8-17
Introduction:
8 For ye were sometimes darkness, but now are ye light in the Lord: walk as children of light:
Last week we finished up at Ephesians 5:8. It is God’s command to “Walk as Children of Light.” Logic requires us to ask, “But what does that mean? How does it look, to “walk as Children of light?”
We observed that the character of light is to “dispel darkness.” And (looking ahead) in verse 13, God says that, as light dispels darkness, it also “makes things visible.” It makes known the things that previously were invisible or (at least) obscure.
God Says, Walk as Children of Light
We saw that 1st John 1:5-7 says, “God is light, and in Him is no darkness at all.” He is not speaking of physical light, made of photons, etc. The light in question is Spiritual, Moral light. God is the ultimate source of all light, spiritual, physical, educational, or moral. He is the One who shines in the darkness, and the darkness can never overpower His light (John 1:5). He says that the only way we can have fellowship with Him is to walk in the Light, as He is in the light.
And we choose to walk with Him, because we want to have fellowship with Him. We want to join Him in His work, reaching a lost world. (See John 4:34) We all started out as the children of wrath, according to Ephesians 2:3. We committed ourselves to the works of darkness, even if we did not admit that to ourselves.
Perhaps it was only the “self-will” that characterizes all humans, and we may not even have seen it as sin. But we begin by confessing that we are…lost sinners. When we see our need for a Savior, and when we place our trust in the completed work of Jesus at the Cross, He counts that faith as righteousness, and He permanently claims us as His own!
So, was that true of me? Was I really a lost sinner? Yes! I truly was! But, should that sin be reflected at all, in my life today? No! I am now a child of God, and therefore a child of light.
I desire to walk in the Light, with Him! So… I need to know how to do that.
What Should “Walking as Children of Light” Look Like?
9 (For the fruit of the Spirit is in all goodness and righteousness and truth; )10 Proving what is acceptable unto the Lord.
The true “goodness and righteousness and truth” that God requires of us is only possible as the result of the Holy Spirit working through us. The full description of the nine-fold Fruit (singular) of the Spirit is in Galatians 5:22, 23. God says that all true goodness, and righteousness, and truth emanates from Himself. “Do-it-yourself” righteousness is not what God requires. In John 15:5, Jesus said, “Apart from Me ye can do nothing!” And He meant exactly that!
He wants us to experience, and demonstrate God’s will in our lives. We show that His Will does work: That the promises of God are valid and good. The word “proving” means to experientially “test the theory,” so to speak. In Industry, there are certain “proof-tests” technicians apply, to ascertain that structures are safe to use. Those tests give the workers in that shop or on that job-site the confidence to use the tools, cranes, manlifts, etc., knowing they have been tested.
We are the continuing demonstration of the Grace of God, working in our own lives. Others will see that demonstration. They may not understand why we are suffering. But the Grace that they see in that suffering will draw them to Christ.
Our lives are supposed to be “living proof” that the Grace of God is alive and functioning in our lives…so unbelievers around us should see the constant invitation to join us in that Grace.
What Does “Light” Do About Sin?
11 And have no fellowship with the unfruitful works of darkness, but rather reprove them.
We don’t like the prospect of “reproving sin”—but our lives will do so, if we are walking in the Light, and, occasionally we will verbally confront evil behavior. If we live the way God says to live, our lives will be demonstrating the shortfalls of the world. (SeeJohn 16:8-11)
And that light will never be popular with people. Other people will accuse you of thinking you are “too good” for them because you have abandoned the life-patterns you once followed. You will be shunned because you no longer fit their pattern.
12 For it is a shame even to speak of those things which are done of them in secret.
It is neither desirable nor profitable to describe, discuss, or “repeat news” of the evil deeds that lost people do. There is some sick part of our old sin nature that loves to hear such things and “experience it vicariously:” But this is a shameful thing in our nature: don’t indulge it!
We sometimes see this pattern in gossip, where one believer tells another, “Let me tell you about this so you can pray about it…” Sorry…God warns against that sort of thing. It is an easy trap to fall into, but He specifically says that it is a shame to speak of such things. Besides, it is also an unloving thing. God says that “love covers a multitude of sins” (1st Peter 4:8), but that it is an evil heart that wants to “tell all.” (Proverbs 11:13)
Light Does “Make Manifest!”
13 But all things that are reproved are made manifest by the light: for whatsoever doth make manifest is light.
We don’t have to get into a detailed discussion of the evil in the world. But if we walk in the light, we can’t help reflecting that light into a sin-sick world: And some people will see themselves in that light, and they will be ashamed. Then, they will either run from the light, or they will turn to it for salvation. (John 3:19, 20) The way they respond to the light reveals the content of their heart. There is a common saying: “The same warm sunlight that softens wax, hardens potter’s clay: That saying is true… but that metaphor assumes that some of us are “made of different stuff.” (Which is not true….)
We All Have The Same Flaw
God says we were all formed of the same dust, so the difference has to be somewhere else. A rat in a barn, at night, runs for cover when someone walks into the barn with a lantern; but it is because the rat has learned that the farmer doesn’t want him there, and will kill him if possible, as a destructive, filthy, disease-carrying animal: a threat to everything the farmer holds valuable.
The finches, however, and the swallows, living among the rafters of the same barn, will respond quite differently. They may actually mistake the light for sunrise, and they may begin to sing. They would be afraid, too, if the farmer got too close to them, but in general, they do not see him as an enemy, and they always welcome the light.
A tame rat, though, raised as a pet, in clean surroundings, does not fear the light. It does not fear people, and is quite bold, as it sees humans as a source for handouts. The squirrels at a park, for example, begging for treats, demonstrate the same idea.
So, Why Do Some Respond In Faith, and Others In Indifference Or Rebellion?
What Is The Difference?
The difference appears to be relational. Before He created the Earth, God chose to receive those who would respond to Him in faith: Those who would believe His Word, allowing His light to dispel the darkness in their souls. Remember: the “thief on the Cross,” who now is famous for his faith, initially was mocking Jesus along with the crowd and the other thief. He did not initially respond in faith: but he repented, confessing that he was a sinner, and asking that Jesus remember him. He responded to the light he saw in Jesus.
Faith Is An Obedient Response To A Revealed Truth.
Abram (“Abraham”) lived in “Ur of the Chaldees” (modern-day Iraq) when God called him. He was not far from ancient Babylon, a center for idolatrous worship, where they attempted the construction of the Tower of Babel. The confusion of languages occurred there only a generation before.
But, God told Abram to leave ther, and Abram went: He partially obeyed. (God told him to leave his extended family behind, but he brought them along; possibly because his father insisted on it.) Later, God called him again, and he still brought his nephew, Lot. But Abram’s life was beginning to demonstrate faith, and worship. Finally, after God separated Abram from Lot, God made him a promise, and, (Genesis 15:6) Abram believed God, and God credited it to him as righteousness.
This is what God is looking for, both initially, in salvation, and as an ongoing lifestyle. Think about how your own life either reflects this or fails to do so: are you really believing God over your own fears and the constant arguments of the World around you? Are you trusting God, on a day-by-day basis? Hebrews 11:6 says Faith is what pleases God. Obedience (as the result of faith) is the fruit of that relationship.
God Calls for a Change!
14 Wherefore he saith, Awake thou that sleepest, and arise from the dead, and Christ shall give thee light.
Since we know that, before we were saved, we were dead in sin; and that when we walk in sin now, we are truly living as “walking dead men,” it is entirely fitting that he would say, “awake, thou that sleepest, and arise from the dead, and Christ shall give you light.”
Do you really want the light of God to rule in your life? Then let go of that old, dead pattern of sin and unbelief, and allow Jesus to fill you with the light of His Word. 2 Peter 1:19 says that the light upon which we are to focus our attention is the written Word of God!
Learning Wisdom
15 See then that ye walk circumspectly, not as fools, but as wise, 16 Redeeming the time, because the days are evil.
Yes, there are many possible “demonstrations of faith and wisdom,” but there seems to be a connection here, when I consider verses 15 and 16 together, and then consider the other parallel passages. Let’s read and compare Proverbs 11:30: “The fruit of the righteous is a tree of life, and he that winneth souls is wise.” Isn’t it interesting that God says a soul-winner is behaving wisely? And, reading on, see what He says about how we use our time:
See Colossians 4:5, 6 “Walk in wisdom toward them that are without…” (unbelieving neighbors and friends) “…redeeming the time. Let your speech be always with Grace, seasoned with salt that you may know how you ought to answer every man.”
Compare, also, 1 Corinthians 15:34 “Awake to righteousness and sin not: for some have not the knowledge of God: I speak this to your shame.” I really don’t think I can safely overlook these connections in God’s Word, nor can I deny that all of these are in direct reference to practical, relational evangelism.
Choose Wisdom!
Romans 10:17 assures me that Faith does come by hearing, and that hearing comes by the Word of God. We are responsible for those in our daily sphere of contact. We cannot simply shrug, and say, “Well, whatever they believe, it is their business, and I ‘don’t feel called’ to try to persuade them to believe something else.” God says that we are called; and we are His ambassadors, and that our primary task is to persuade men, and reconcile them to God. (2nd Corinthians 5:18-20.)
17 Wherefore be ye not unwise, but understanding what the will of the Lord is.
How am I going to know God’s will? I am to begin by looking in His Word. Only there will I learn the principles by which He wants me to live. God says I am to learn wisdom there—learn to make good decisions habitually—and to learn to have the same values as God does. (Jesus stated His priorities in John 4:34) Then I can hope to find the life of obedience to be a sweet experience rather than bitter drudgery, and I can learn how to guide my steps.
I want my life to count for eternity. The only way I can hope to see that outcome, is if I allow Jesus to work through me. I cannot achieve eternal re4sults working with temporal tools. Only Jesus, as the Author of our faith, and the only source of eternal life, can achieve eternal results.
Lord Jesus, we desire to see our lives transformed into Your likeness. We desire to be transformed from the inside, out, and sow the seeds of righteousness and peace, and see lives changed by the Gospel. Fill us with Your Holy Spirit and allow us to serve.
