He who says, “I know Him,” and does not keep His commandments, is a liar, and the truth is not in him. But whoever keeps His word, truly the love of God is perfected in him. By this we know that we are in Him. He who says he abides in Him ought himself also to walk just as He walked.
Listen to the "Verse by Verse" episode covering this scripture.
The apostle John also recorded in his Gospel these words of Jesus Christ: “If you love Me, keep My commandments” (John 14:15).
As we saw in passages like Mark 1:21, Mark 6:2 and Luke 4:31, Jesus Christ set the example of keeping the Sabbath, one of God’s 10 Commandments.
The Bible tells us to follow His example and “walk just as He walked.” This includes remembering the Sabbath day, as the New Testament Church and the apostles, including the apostle Paul, did.
