Isaiah 65

Am I guilty of not praying a prayer that God is ready to answer? Has there been an obstacle that fell in my path because I did not pray for deliverance? Has this economic downturn endured because I have not joined with believers in petitioning God. Are Christians in Sudan impoverished because I have not faithfully sought the heart of God with their plight? God does not need our prayers to act. Yet he may wait on the prayers of his church so that we will recognize when he has acted.
