In Daniel 2 "And in the second year of the reign of Nebuchadnezzar Nebuchadnezzar dreamed dreams, wherewith his spirit was troubled, and his sleep brake from him. Then the king commanded to call the magicians, and the astrologers, and the sorcerers, and the Chaldeans, for to shew the king his dreams."
Nebuchadnezzar had a dream that kept him up at night. He was so disturbed by it that he called on the magicians and astrologers for its meaning. They said "tell us the dream and we'll tell you what it means. He told them no, he couldn't remember it. They had to both tell him the dream AND interpret it! And if they couldn't, he would destroy them all.
And important thing to note here is that people dream all the time and we mostly forget our dreams. But this dream mattered, and Nebuchadnezzar knew it mattered, that's why it bothered him so much that he couldn't remember it.
Kind of sounds like me. God gave me a dream and I didn't understand it (or didn't want to). It kept me up at night. I called on God to help me. I also told God "not only must you tell me the dream, but you have to interpret it for me. You have to also show me exactly how to make the dream come true; where must I go and what must I do. Take my hand and walk me step by step through bringing this dream to life! And if you don't, I'm going to leave it sitting right here."
How arrogant of me. First, to tell God what He's gonna do! But secondly, to assume that God wouldn't equip me for the dream in the first place.
The dreams God gives us matter. We know they matter and that's what terrifies us so much. We don't want to get it wrong, or disappoint God or, worse yet, fail. That's me. I don't want to fail. I don't want to step out on something that God gave me and then totally bungle it up.
But God is God. He doesn't make mistakes. He wouldn't ask me to do something that He hasn't equipped me for. But that means I must take advantage of the equipment (the Word, Study, Prayer, Worship, my faith, His strength, etc.) that He provides for me.
And then I just have to do it.
Trust the dream that God has given you. Trust that He has provided you all you need to accomplish it. Trust in him and then just do it. And watch God work.
