57 Yahweh is my portion; I have promised to keep Your words. 58 I have sought to please Your face with all my heart; Be gracious to me according to Your word. 59 I thought upon my ways And I turned my feet to Your testimonies. 60 I hastened and did not delay To keep Your commandments. 61 The cords of the wicked have encircled me, But I have not forgotten Your law. 62 At midnight I shall rise to give thanks to You Because of Your righteous judgments. 63 I am a companion of all those who fear You, And of those who keep Your precepts. 64 The earth, O Yahweh, is full of Your lovingkindness; Teach me Your statutes. Psalms 119:56-64 (LSB)
God does not need us. God is holy; therefore, He is fully fulfilled in Himself. His holy attributes show us His perfection and infinite power. At the fall of man, found in Genesis 3, God would have been perfectly justified in wiping out Adam and Eve then starting over. However, He did not. Praise the Lord He did not! God was merciful to Man whom He loves. He still is.
Man does not deserve God’s mercy. That is why it is an act of grace for God to be merciful to Man. The fall of Man into sin is called the Original Sin. This act of disobedience by Adam altered his lineage so all of his descendants inherit his sin nature. All male and female human beings born since Adam and Eve are born Totally Depraved. That does not mean all men; women, boys, and girls are wicked all the time. What that means is the heart of Man was corrupted by the Original Sin so he cannot and will not seek God. In fact, from birth, all people are born spiritually dead and are enemies of God.
