When Jeremiah the prophet was a boy, he had a life altering encounter with God. You can read about it in Jeremiah 1:1-19.
At one point, God tells him that he is going to speak through him to challenge leaders in powerful positions of authority. Jeremiah raises the objection that he is only a boy. The Spirit quickly confronts him says “Don’t say I am only a boy“.
The thought comes to mind that I say all kinds of things that limit what God wants to do through me. It usually sounds a lot like… “but I’m only…”
Oh Creative God, teach me to fill my head with your thoughts about me and learn to echo what you say about my potential in your hands.
