15 God also said to Moses, “Say to the Israelites, ‘The Lord, the God of your fathers—the God of Abraham, the God of Isaac and the God of Jacob—has sent me to you.’
“This is my name forever,
the name you shall call me
from generation to generation.
16 “Go, assemble the elders of Israel and say to them, ‘The Lord, the God of your fathers—the God of Abraham, Isaac and Jacob—appeared to me and said: I have watched over you and have seen what has been done to you in Egypt. 17 And I have promised to bring you up out of your misery in Egypt into the land of the Canaanites, Hittites, Amorites, Perizzites, Hivites and Jebusites—a land flowing with milk and honey.’ Exodus 3:15-17
The Lord gave Moses a very tall order. I completely understand how Moses might have been intimidated by it, though he started with the excuses before he knew what the assignment was.
If I were Moses, I’d be asking why.
How could you possibly use a cowardly murderer like me?
And there again is the point, isn’t it?
God has used and will continue to use flawed humans since He created us. What better way to reveal his mercy and grace than through a completely compromised individual. It certainly doesn’t give us license to commit these atrocities ourselves, thinking that’s the only way to get God’s attention and for Him to use us.
No, God uses His people in spite of their past (and some would argue because of their past) for His glory.
If He is calling you to do something you feel inadequate to do, rest assured, He will give you what it takes to do the job, again, for His glory.
