God is Patient
Psalm 103:8 goes on to tell us that God the Father is slow to anger. In Hebrew, it literally means He is long in anger. This means it takes an awful long time for the Father to get angry. It is because He is compassionate and gracious. Many misunderstand the Old Testament. They find in it an angry God. What they don't notice is the chronology. God may talk about judgment through the prophets, but it takes hundreds of years and many rejected opportunities for repentance, for God's anger to break out. God is not an ill-tempered dad. He recognizes that change in our lives is difficult and so He wants to win us and WOO us through grace.
As God sympathetically understands where we are in life and graciously responds to our true needs, He ends up being very patient with us. Again, these are the leading characteristics of the God and Father of our Lord Jesus Christ. When we sin, we are sinning against niceness. We are not sinning against a nasty dictator. As Jonah said in Jonah 4:2-3, “I know that you are a gracious and compassionate God, slow to anger and abundant in loving kindness, and one who continually repents concerning evil. Therefore now, oh Yahweh, please take my life from me, for death is better to me than life.” Jonah did not want to live in the world with such a God as he described. We should be very happy to live with such a God.
