Sin places a wall between the sinner and God. The only way to remove the distance between God and man is to remove what has brought about the distance-and that is sin. Sin is to miss the mark. Sin is disobediance to the Word and will of God. Sin is destructive.
Sin is lust concieved in the heart.
No one has made anyone sin. The devil cannot make you sin. Sin is an act of the will. A matter of choice. A given decision to ignore the word of the Lord.
