Then Jesus spoke to them again, saying, “I am the light of the world. He who follows Me shall not walk in darkness, but have the light of life.” (John 8:12, NKJV)
Jesus illuminates this world with truth. As the light of the world, Jesus exposes the world with His light. The powerful truth of Christ’s word lays bare the darkness of sin in all its futility, foolishness and falsity. “The light shines in the darkness, and the darkness did not comprehend (overcome) it” (Jno. 1:5). Sin does not overwhelm the light of Christ. As the light of the world, Jesus judges the world. In the last day, His word will judge all who reject Him (Jno. 12:48). By walking in His light you avoid the future condemnation of sin. As the light of the world, Jesus saves the world. He shows the way out of sin; the way to the Father. “In Him was life, and the life was the light of men” (Jno. 1:4). Rejoice and thank God each day that Jesus is “the true Light which gives light to every man” (Jno. 1:9). His true light of truth is “already shining” (1 Jno. 2:8). Follow Jesus. Walk in the light of His truth and be led to eternal life.
5 O house of Jacob, come and let us walk in the light of the Lord. 6 For You have forsaken Your people, the house of Jacob, because they are filled with eastern ways; They are soothsayers like the Philistines, and they are pleased with the children of foreigners. (Isaiah 2:5-6, NKJV)
Judah and Jerusalem had turned away from Jehovah, the only true source of truth and guidance. Because they listened to and trusted in pagan soothsayers and refused to listen to God’s word, God would now leave His people exposed to divine judgment. (Read Isaiah 2:5-22 for a fuller picture of Jerusalem’s sins and God’s promised punishment.) Like Jerusalem of old, Christians must choose whether to walk in the light of the Lord or in the darkness of the world’s error (1 Jno. 1:6-7). When Christians turn to false sources of knowledge and wisdom to guide them, they walk in the darkness of sin and fall under God’s promise of eternal punishment (1 Jno. 1:6; Jno. 12:48). With Isaiah we exhort, “Come and let us walk in the light of the Lord.”
12 The night is far spent, the day is at hand. Therefore let us cast off the works of darkness, and let us put on the armor of light. 13 Let us walk properly, as in the day, not in revelry and drunkenness, not in lewdness and lust, not in strife and envy. (Romans 13:12–13, NKJV)
The dawn breaks and beams of sunlight burst upon the land. The night is over; time to rise and shine and meet the challenges of the day. The darkness of night lends itself to the indecencies of sin. But, Christians are “light in the Lord” – children of light who follow Christ, the light of the world (Eph. 5:8; John 8:12). Christians are admonished to get rid of every vestige of sin and clothe ourselves with the armor (or, weapon) of light. As light diffuses darkness, we must reject every indulgence of the flesh. Sin dwells in dark places of the heart and lures unsuspecting Christians to fulfill its lusts. It is time to clean up your heart and walk decently. The light of the Son is shining. Walk in His light. Live by His truth today.
8 For you were once darkness, but now you are light in the Lord. Walk as children of light 9 (for the fruit of the Spirit is in all goodness, righteousness, and truth), 10 finding out what is acceptable to the Lord. 11 And have no fellowship with the unfruitful works of darkness, but rather expose them. 12 For it is shameful even to speak of those things which are done by them in secret. 13 But all things that are exposed are made manifest by the light, for whatever makes manifest is light. (Ephesians 5:8-13)
Christians are “light in the Lord”. We do not live in the shadowy recesses of sin and shame. This passages calls us to the following actions: 1) Walk as children of light. Goodness, righteousness and truth are “acceptable to the Lord” and is the fruit our life must bear. 2) Have no fellowship with sin. To practice, teach, endorse or otherwise approve of sin and those who practice it puts one in fellowship with sin. 3) Reprove the works of darkness (sin). That is, expose sin for what it is; shameful before God and those who love God. Do not approve it. Do not be entertained by it. Do not compromise with it. Stand up against sin and call the lost to repentance. You were once in sin’s darkness, too. Now, you are a child of light. Live like it every day.
