“God’s call is almighty, and very different from my call. I’m a preacher; I call you to faith every week. I call you to love God; I call you to follow Christ; I call you to embrace Him; I call you to treasure Him. I call you week after week, and that is not the same as the divine call.

What’s the difference? My call is general, God’s call is specific.
My call offers hope, God’s call creates hope. My call offers life,
God’s call, in and through mine, gives life. My call commands you to love God, God’s call through mine grants what He commands.” - John Piper “All things for Good, Part 3a”, Desiring God Radio 3/28/07
