Look at Amos in the Bible. He was not a prophet or priest or son of either. He was a shepherd and a small businessman in Judah. Would anyone listen to him. He wasn't like Moses and made excuses but he obeyed God and became God's powerful voice for change.
So I am not going to feel like a "justa" anymore and I hope that you don't want to feel that way either. We have a great adventure down the road. It may be hard but if God is with us we can do anything and do it well.
Have a great day!
