If you are doubting the power of the little things you are doing, then this message is for you.
We tend to think that only the great things done to God are the significant ones. We often think that if we want to please the Lord, we should start a church, go on missions, do miracles, etc. and etc. But those are not the only thing that pleases the Lord.
Your little actions of faith could change the whole world! And this is the proof!
