“The one who says, “I have come to know Him,” and does not keep His commandments, is a liar, and the truth is not in him; but whoever keeps His word, in him the love of God has truly been perfected. By this we know that we are in Him:” 1 John 2:4-5 (NASB)
We have two verses today but are looking mostly at the second one for our promise. The use and repetition of the words know and keep emphasizes that those genuinely born again display the habit of obedience. Obedience results in assurance of salvation. God has given us many instructions in the Bible and we realize that He expects us to obey them. Someone may profess a fellowship with God but how they live their life shows they do not possess. John was not shy to call this kind of claim what it really is: a lie. Moreover, it may be said of the same person that the truth is not in him. If we truly love God we will want to live a way that is according to what He wants us to live. We obey God’s word and our love for Him is demonstrated. We show our love through obedience. When we obey God’s word His love for us is also demonstrated and His love for us is made perfected. He has given us instructions because He loves us and knows what is the best way for us is to live.
