Whose fault is it?

When we sin it is no one's fault but our own. It is not Adam's fault. It is not any other person's fault. It is not the devil or any of the demon's fault. It is certainly not God's fault. It is your own fault if you sin. Let no man say when he is tempted, I am tempted of God: for God cannot be tempted with evil, neither tempteth he any man: [14] But every man is tempted, when he is drawn away of his own lust, and enticed. [15] Then when lust hath conceived, it bringeth forth sin: and sin, when it is finished, bringeth forth death. James 1:13-15 The soul that sinneth, it shall die. The son shall not bear the iniquity of the father, neither shall the father bear the iniquity of the son: the righteousness of the righteous shall be upon him, and the wickedness of the wicked shall be upon him. Ezekiel 18:20
