Why should we pray?
The short answer is that God commands it. “Call upon me, and I will answer thee and show thee great and mighty things thou knowest not.” Jeremiah 33:3. Prayer is communication between us and our Heavenly Father.
Jesus said that men ought to pray. He chided his disciples for falling asleep instead of praying with Him. “What, could you not watch with me one hour?” Mark 14:37
