It is our worst enemy. Sin is like a snake, full of deadly poison. It is like a little spark that can burn up a great forest. Sin is lawlessness . He who does what is sinful is of the devil, because the devil has been sinning from the beginning.
Sin is the force that moves in the members of our bodies and fights against what is true and good.
Sin is anything that does not agree with the will of God. Sin is refusing to believe and obey the Word of God. To go my own way is sin. Those who come by the way of salvation that God has decreed will be granted eternal life. But those who harden their hearts against the truth will face God's wrath and judgment.
