So many scientist/atheists/agnostics believe that prayer is a form of "alternative medicine". Most people especially the atheists believe that prayer is just a waste of time, that no one is listening.
In contrast, the bible presents prayer as much more than just a form of therapy. It tells us that someone really is listening to prayer that are made in the right way and for the right things. Like friends communicate with each other to cultivate a good relationship, God invites up to talk to him in prayer, opening the way for warm friendship. He says: " You will call me and come and pray to me, and I will listen to you."(Jeremiah 29:12). As you speak to God, you will "draw close to [him], and he will draw close to you" -James 4 : 8
What does prayer involve?
The bible shows that prayer can embrace every facet of our life. Prayer may include:
i. confession {psalm 32:5}
