He is the atoning sacrifice for our sins, and not only for ours but also for the sins of the whole world. (Love and Hatred for Fellow Believers) We know that we have come to know him if we keep his commands. Whoever says, “I know him,” but does not do what he commands is a liar, and the truth is not in that person.
1 John 2:2-4 NIV
The person who is well acquainted with the Lord will not be a stranger to HIs commandments.
