God can give us the words we need.

Exodus 4: 10-12

10 And Moses said unto the Lord, O my Lord, I am not eloquent, neither heretofore, nor since thou hast spoken unto thy servant: but I am slow of speech and of a slow tongue.

11 And the Lord said unto him, Who hath made man’s mouth? or who maketh the dumb, or deaf, or the seeing, or the blind? have not I the Lord?

12 Now therefore go, and I will be with thy mouth, and teach thee what thou shalt say.

Many people fear to witness to others about God, while in some ways in this day and age it is somewhat justified. Talking about God with the wrong people can get you fired,  cause arguments, lose friends, and in some places get you killed. Moses was about to be in one of those situations. He was about to go face to face with the Pharoh, who had the legal authority to kill him.   He was scared and had a right to be, but he was not alone. God was with him.  Yes, witnessing can be scary, but God has your back. He can use anyone or anything he wants to accomplish his will.  He does, however, prefer to use those who want to be used to accomplish his mission.  If you desire to be close to him, and carefully study who he is, he will give you the words you need when it matters most. Sometimes it will come at an earthly cost, but our reward in Heaven will make up for anything we lose here. Fear Not!
