Do we really understand that prayer is simple conversation with Father God? We can talk to Him as we would a loving earthly parent. We do not have to have a particular stance or attitude. He is longing to be in conversation with us, to provide for our every need.
Be joyful in hope, patient in affliction, faithful in prayer. This does not mean that life is a fun ride until we graduate to Heaven. There are times in our christian walk when we hope for things that never arrive, there is affliction, but in all situations we can to pray.
