Exodus 5:22-23 (KJV)

22 And Moses returned unto the LORD, and said, Lord, wherefore hast thou so evil entreated this people? why is it that thou hast sent me?

23 For since I came to Pharaoh to speak in thy name, he hath done evil to this people; neither hast thou delivered thy people at all.

We all doubt when we don’t see what He promised, but we need to know that He will do as He promised and keep trusting in Him
