Psalm 17

Because of our sin and our separation from God there will always be some level of dissatisfaction in everyone's life. Our missing fellowship with God will flicker all through our lives; even among those who reject God's grace. For those of the faith our realization of the alienation from God should build in us an ever growing hunger for more of God. That hunger will make us stumbling blocks to those people who have quenched the flame of God's image in us. They will become annoyed by our piety and angered by the righteous heart that God creates within us. In verse 13 David points out that he needs God's rescue from those who find their satisfaction in the emptiness of this life. Jesus faced the same situation from the same group of people in his day. We too will encounter similar people and attitudes.
