The Bible does not equate perfection with sinlessness. Though that is the perfect will of God for us, however, He makes provisions for our restoration if we sin. Perfection should be understood as Christian maturity. It is better stated here: “The Bible speaks of maturity in terms of a Greek word often translated “perfect,” but the meaning is “fully formed” or “brought to completion,” and that takes time. Maturity is not so much a destination as it is a journey or road full of twists and turns.” (http://dev.guidelines.org › devotional › what-does-it-mea…).

“To walk in love is to walk in perfection.”

For a clearer understanding of this issue, we will consider the context in which Jesus used the word. In His teaching on the mount, He treated how we should treat our enemies. He instructed us to love our enemies, following in the footsteps of the Heavenly Father who gives rain and sunshine to both the just and the wicked. He concluded that treatise with this: “Therefore you shall be perfect, just as your Father in heaven is perfect.” (Matthew 5:48 NKJV). In context, He regarded love as perfection. To walk in love is to walk in perfection. Paul’s submission agrees with this. In Romans 13:10, he said, “You can’t go wrong when you love others. When you add up everything in the law code, the sum total is love.” (MSG). “You can’t go wrong when you love others” means you are perfect walking in love.
