Throughout the Scriptures, God teaches that man cannot live without Him. Indeed, mankind may survive and exist, but true life can only be found in God. Once a person has believed in Christ as his Savior, he receives this promised life. And the lifeline of this life is prayer.
Prayer is simply communication with God. It may not have elaborate words, or complicated rituals. What God wants to hear from His people is a request that comes from an open and humble heart. What does prayer achieve? It works wonders, not just in the physical world, but in the spiritual world as well.
Prayer has power not because of the one praying, or the item being prayed for, but the One who answers and grants it. If we truly believe that God is faithful to His word, and we align our prayers in His will, we will certainly receive what we pray for.
