Judges 6:16 The Lord answered "you can do it because I will help you, you will crush the midianites as easily as if they were one man".(Goodnews bible)
The above Was the word of the Lord to Gideon, but this day it His word to you.
Often time,when God commits a task to us, give us an idea, Just like he did with Gideon, we are scared, unsure of ourselves, our capabilities; we let our tribe(clan), language, etc. limit us. God is telling you today,YOU CAN DO IT BECAUSE I WILL HELP YOU.
If God says he will help you, consider the mission/task accomplished.
Trust him, lean on him. Our God is limitless..
Next time the I can't thought come, say I can because God will help me.
