Does the fear of not knowing what to say keep you from saying something that you need to say?
Listen to what God said to Moses in Exodus 4: 10 to 12
But Moses pleaded with the LORD, "O Lord, I'm not very good with words. I never have been, and I'm not now, even though you have spoken to me. I get tongue-tied, and my words get tangled." Then the LORD asked Moses, "Who makes a person's mouth? Who decides whether people speak or do not speak, hear or do not hear, see or do not see? Is it not I, the LORD? Now go! I will be with you as you speak, and I will instruct you in what to say."
Will you trust in God and boldly speak up as He instructs you in what to say?
