The love of God is perfected in a person’s life when he or she obeys from the heart the words of Christ (Rom. 6:16-18); without obedience, one has not reached a mature state (1 Jn 2:5). Perfection is not a matter of being flawless or sinless (in this context), but the willingness and desire to allow the will of God to control one’s life. It was Jesus who said to those around Him, “Why do you call me ‘Lord’, ‘Lord’ and do not the things that I say?”
