Prayer is simply talking to God. As in any close relationship, the more you communicate the stronger the bond is between you. I think we make prayer more complicated than God ever intended. Listen to what David says in Psalm 139
O Lord, you have searched me and you know me. You know when I sit and when I rise; you perceive my thoughts from afar.
Since God already knows your every thought, why not tell him honestly how you are feeling? Take time right now and just tell him what is on your heart. Remember God loves you and is waiting to hear from you.
I absolutely agree that we make prayer more complicated than God meant for it to be. If we read Jesus’ example in the Lord’s Prayer, we see that He used simple phrases from His heart. Speaking to God. as a friend, without all the fancy words, and knowing He listens to EVERY word is the greatest comfort of all!
