Eze 18:4 Behold, all souls are mine; as the soul of the father, so also the soul of the son is mine: the soul that sinneth, it shall die. Eze 18:20 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. When you sin you die or you start withering spiritually. A branch cut off from the vine dies and so is what happens when we sin and remain in sin. Staying with unconfessed sin cuts us off from the vine. Sin is a killer and kills! It is stronger than any man-made weapon. When you sin you are cut off from the vine and spiritual nourishment then you start dying. Your conscious slowly dies, your self-awareness slowly dies, etc and the evil crops in to take full control of you and you start bearing fruits accordingly. Rom 6:20 For when ye were the servants of sin, ye were free from righteousness. Rom 6:21 What fruit had ye then in those things whereof ye are now ashamed? for the end of those things is death. Rom 6:22 But now being made free from sin, and become servants to God, ye have your fruit unto holiness, and the end everlasting life. Rom 6:23 For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord.
