John 12:35-37 WEB
Jesus therefore said to them, “Yet a little while the light is with you. Walk while you have the light, that darkness doesn’t overtake you. He who walks in the darkness doesn’t know where he is going.  While you have the light, believe in the light, that you may become children of light.” Jesus said these things, and he departed and hid himself from them.  But though he had done so many signs before them, yet they didn’t believe in him,
What does it mean to walk in the light? It means a person who believes in Jesus and walks according to his teachings. The deeds of the light are mercy, justice, and humility (Micah 6:8). That is what walking in the light meant 2000 years ago and it still means the same thing today. Believers today must still walk in the light. When a person is walking in the light, they are obedient to the Bible. People walking in the light are convinced that all sin is darkness.
There are several sin lists in the New Testament. Romans 1:29-30 is one of those lists. Some of the things on this list might be a surprise. For example, gossip is grouped with murder. Also, from the same verses boasting and arrogance are also compared to murder. When we walk in these sins and have no urgent desire to stop sinning, we are walking in the dark. When we walk in the light, our sin is a great burden. When we walk in the dark it sounds foolish to repent of sin and walk in the light (Cor 1:18).
An urgent desire to stop sinning is apparent in the life of a person walking in the light. The deeds of walking in the light are different than the deeds of darkness. In the light people visit orphans and widows (James 1:27). They guard their hearts and mouths turning away from evil speaking and evil deeds (John 17:15). People in the light are healed and delivered from sin (Romans 12:2). And righteousness is their heart’s desire (John 2:29).
Lord, give me the grace to recognize and turn away from sin. Please help me read the Bible and give me an understanding of the Bible. I long to walk in your commandments, Lord. Please help me to embrace righteousness and walk in the light.
