Jeremiah 32:27 (New International Version)"I am the LORD, the God of all mankind. Is anything too hard for me?"
*I will say, though, that it is easy for us to project our feelings on God, which may be seen as "over-spiritualizing" something. For example: "I just didn't have peace about it..." The problem with that is that God's peace is not circumstantial. If someone's afraid or they just don't want to do something, then they should just admit it instead of blaming God.
