The Scriptures teach us to seek for the sanctification to God of body, soul, and spirit. In this work we are to be laborers together with God. Much may be done to restore the moral image of God in man, to improve the physical, mental, and moral capabilities. Great changes can be made in the physical system by obeying the laws of God and bringing into the body nothing that defiles. And while we cannot claim perfection of the flesh, we may have Christian perfection of the soul. Through the sacrifice made in our behalf, sins may be perfectly forgiven. Our dependence is not in what man can do; it is in what God can do for man through Christ. When we surrender ourselves wholly to God, and fully believe, the blood of Christ cleanses from all sin. The conscience can be freed from condemnation. Through faith in His blood, all may be made perfect in Christ Jesus. Thank God that we are not dealing with impossibilities. We may claim sanctification. We may enjoy the favor of God. We are not to be anxious about what Christ and God think of us, but about what God thinks of Christ, our Substitute. Ye are accepted in the Beloved. The Lord shows, to the repenting, believing one, that Christ accepts the surrender of the soul, to be molded and fashioned after His own likeness.  {2SM 32.3}  

Romans 3:25  Whom God hath set forth to be a propitiation through faith in his blood, to declare his righteousness for the remission of sins that are past, through the forbearance of God;

1 John 2:2  And he is the propitiation for our sins: and not for ours only, but also for the sins of the whole world.

1 John 4:10  Herein is love, not that we loved God, but that he loved us, and sent his Son to be the propitiation for our sins.
