Now that you have purified yourselves by obeying the truth so that you have sincere love for each other, love one another deeply, from the heart. (I Peter 1:22)
This is a beautiful verse. Peter reminds us that after we have obeyed the truth by believing the gospel that we naturally have a genuine love for other people. He is urging us therefore, to act out this love from the bottom of our hearts.
Only true Christians, however, can act out true love, because “sincere love for each other” can only come by “obeying the truth.”
