Let us consider what is prayer and why pray if God already knows what we need/are asking for?
Some think that prayer is tantamount to an Amazon wishlist the advertized title of which is, “Get what you want”—reminder to self: sign up for an Amazon wishlist :o)
Yet, the primary purpose of prayer not asking for stuff; it is expressing appreciation, thanksgiving it is communion, communication building and sustaining relationship with God through the Messiah Jesus. The fact that we ask, or are asked, questions such as why bother praying if, as the Bible states it, “Your Father knows what you need before you ask him” (Matthew 6:8) shows that when it comes to the Bible, to God, to biblical Christianity the spiritual warfare is on and our minds are its victims.
How so? Because the issue is so very simple and we would not ask wonder about such things in any other context.
Examples:
My wife knows that I love here therefore, I will no longer tell her that I love her. If she asks why I no longer do that which was an, at least, daily habit I will simply say, “Well, you already know it, right!?”
I am helping you fix your car, you are underneath, I am handing you the tools. I already know that you will need the thingamajig when you get to the whatchamacallit. So, why did I not hand you the thingamajig already since I already knew that you would need it? Why wait until you ask for it? Because giving it to you before you needed it would have cluttered up things and because it was previously unnecessary.
Also, what if you get to the whatchamacallit, ask me for the thingamajig but I say, “No”? What? That is right, I say, “No, actually; in order to fix the whatchamacallit you should not use the thingamajig but a doohickey” or “No, actually; before getting to the whatchamacallit you need to deal with the thingamajob.”
We engage upon relationship with God through prayer and know that when and if we ask for something God will say yes, no or wait (see Atheism, EvilBible.com and Jesus Lied for a consideration of the issue of God’s responsibility in answering our prayer).
