Exodus 4:1 And Moses answered and said, But, behold, they will not believe me, nor hearken unto my voice: for they will say, The LORD hath not appeared unto thee.Moses had heard God speaking to him and still doubted that anyone would believe that God had sent him. He was afraid that no one would pay him any attention. That is a fear that we all face. We have the very Word of God. We have the Holy Spirit dwelling in us but it is still easy to doubt that anyone will listen. But the God that called you forth will take care to use you for His honor and glory. He will speak. Lives will be changed. Do not sit on the sidelines and miss what God is doing in and through those that He sends to do a work. You speak and leave God to do the work. He works in the lives of men and women as we speak.
