I remember one time when I was praying, I started out sitting on my bed with my eyes closed. I remember getting annoyed and angry. So, I stood, but I was still in prayer. I remember just talking and venting because I had no one that will listen. I started shouting and yelling on my feet. I wanted so much to cry, but my annoyance overtook my sorrow. I was praying in frustration up until I found myself knees bent to my bed asking for more strength.
You know, I honestly think it's all on you and your heart when you communicate with Him in prayer.
