1Jn 2:1 My little children, these things write I unto you, that ye sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous:
Throughout the scriptures we consistently find the standard for Christian conduct: we are to live a holy life, to strive to live without sin. There can be no other goal for one who loves God above all else and loves his neighbor as himself. We cannot tolerate sin in ourselves; however, we are also reminded that our God is a merciful God. We are to strive to live above sin, but if we fall, we need not despair. Repent, God will forgive. Then resume your Christian life with new determination to avoid sin.
