Jesus didn’t come to the Earth and live a perfect sinless life to be a dead sacrifice. He came to be a living example! He wants us to keep his law.
Jesus said in Matthew 5:48 KJV Be ye therefore perfect, even as your Father which is in heaven is perfect.
Certain men say you cannot be perfect. I don’t believe Jesus would have told us to do something that is impossible. Rather I believe with Jesus all things are possible. He can help us to walk perfectly and sinless before the Heavenly Father.
Remember in Ecclesiastes 12:13 Solomon said, Let us hear the conclusion of the whole matter: Fear God, and keep his commandments: for this is the whole duty of man.
Therefore we strive for perfection with Jesus’ aid.
