If you don’t know this for sure, then I offer you a way to prove it. Prayer is your opportunity to develop intimacy with the living God.
Very often I’ve failed to know this truth myself because I practiced was praying selfishly. I treated God as my personal genie—rub his belly and he was supposed to perform. Silly me. I had it twisted, God doesn’t exist for my pleasure nor to do my bidding.
I believe the Lord God intends our relationship to be completely intimate. Prayer is a part of that intimacy. I’d like for you to experience why this is so.
