Whenever I think of Moses and how God used him to free the Israelites from Egypt, I think of Charlton Heston in The Ten Commandments.
Read Exodus 3 – 6 and you find a quite different picture. Moses constantly begs God to send someone else, and whines about the difficulties of talking with Pharoah, at first.
Thankfully, by chapter 7, Moses seems to settle into his role, though Aaron is still the one that does the talking for him.
I find it encouraging that God uses Moses in spite of his nerves and weaknesses.
I also find it encouraging that Moses eventually does gain enough trust in God to stop whining about every difficulty and just do what is asked of him.
May you also find comfort and encouragement for whatever lies ahead of you in the account of Moses.
