1 John 1:5-10, KJV
5This then is the message which we have heard of him, and declare unto you, that God is light, and in him is no darkness at all.6If we say that we have fellowship with him, and walk in darkness, we lie, and do not the truth:7But if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin.8If we say that we have no sin, we deceive ourselves, and the truth is not in us.9If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.10If we say that we have not sinned, we make him a liar, and his word is not in us.
“Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven,” Matthew 5:16, KJV. Where does this light come from? The light is Jesus. The light is walking uprightly before the Lord. The light is the goodness of God allowing Him to operate in our lives. “Ye are the light of the world. A city that is set on an hill cannot be hid,” Matthew 5:14, KJV. We are his tools in which He uses to share His goodness. “For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them,” Ephesians 2:10, KJV.
But let us not be deceived into thinking that because we know a few scriptures that we are saved and walking in the light--the knowledge of scriptures does not save a person. Prime example: the devil. He knows scripture and even tried to use them against Jesus. Rather we must apply those scriptures to our lives. “If we say that we have fellowship with him, and walk in darkness, we lie, and do not the truth.” We wouldn’t be deceiving God, we’d only be misleading ourselves in thinking this way. And just as the Bible states, we lie about having fellowship with Him if we walk in darkness. Let each man examine himself.
