Psalms 37:9 I have been afflicted and greatly humbled. I bellowed from the groaning of my heart.

When we realize the reality of sin and the separation it causes between us and God, we feel the emptiness. When we realize that God has loved us even to giving his life for our salvation, and yet we sin, we feel ashamed of our selfish stupidity. Imagine what Peter experienced after his denial of Jesus three times, which Jesus has predicted. Imagine when he experienced the merciful glance of Jesus afterwards how bitterly Peter sobbed from the depths of his being. He was humbled, ashamed, filled with remorse and guilt, but he didn’t despair like Judas. In his sorrow he sought forgiveness. Weep for your sins but know the mercy of God.
