Exodus 4:
10: But Moses said to the LORD, "Oh, my Lord, I am not eloquent, either heretofore or since thou hast spoken to thy servant; but I am slow of speech and of tongue."
11: Then the LORD said to him, "Who has made man's mouth? Who makes him dumb, or deaf, or seeing, or blind? Is it not I, the LORD?
12: Now therefore go, and I will be with your mouth and teach you what you shall speak."
Psalm 33
8: Let all the earth fear the LORD, let all the inhabitants of the world stand in awe of him!
9: For he spoke, and it came to be; he commanded, and it stood forth.
10: The LORD brings the counsel of the nations to nought; he frustrates the plans of the peoples.
11: The counsel of the LORD stands for ever, the thoughts of his heart to all generations.
12: Blessed is the nation whose God is the LORD, the people whom he has chosen as his heritage!
13: The LORD looks down from heaven, he sees all the sons of men;
14: from where he sits enthroned he looks forth on all the inhabitants of the earth,
15: he who fashions the hearts of them all, and observes all their deeds.
16: A king is not saved by his great army; a warrior is not delivered by his great strength.
17: The war horse is a vain hope for victory, and by its great might it cannot save.
If you are chosen as one of God's believers and finally calm down. I can share many details that God provided for me during my 37 years of obeying His commandments. He knows every tiny detail of His creation. It's totally amazing how He can do that.
