“But Moses said to God, ‘Who am I that I should go to Pharaoh, and that I should bring the children of Israel out of Egypt?’"
Moses’ question seemed like a good one. He had, after all, once killed a man and had been living as a fugitive. But God’s answer back to Moses was even better than the question. God said, “I will certainly be with you (Exodus 3:11-12).”
God is not concerned about what we have done in the past, and He is not bothered by the fact that we are incapable of doing anything good on our own. All He asks is that we be obedient to follow Him in any way that He leads us. He will be with us, gifting us and guiding us through the Holy Spirit.
Are you involved in your local church? God called Moses to get involved, and He didn’t allow Moses to make any excuses. Each time Moses objected God was quick to remind Moses that He would be with him, and that He would put other people in Moses’ path that would help him out.
If God has called you to get involved in some way then don’t waste time making excuses. Acknowledge the fact that He called you because He knows that you are capable of success because He will be your strength. Trust God and do what He leads you to do.
