When you allow the Lord to work through you, you can accomplish very amazing things!
When you do things for the church with the hopes of Salvation, that is a deception.
It is a deception, and that's putting the cart before the horse. You should
Believe first, in faith (without seeing)
It always makes me smile when someone says, I want to see proof that God exists, then I can have faith in Him, and that aint right. We have to look to what we can not see. We have Faith in God, and Hope. But if one sees before they have Faith, then it isn't Faith anymore! Because we can see it and prove it. No faith in seeing it. No, we are to have hope in what we can not see and Believe in it and Him so act on it, walk in it, do it every day. There is your Faith.
When scripture says, for those with eyes to see, it doesn't mean our physical eyes. When scripture says listen for those who have ears to hear, that doesn't mean you use your fleshly senses to hear what He is saying! It's actually easy once you get used to it.
You have to forget all of your worldly intellect and listen to the unseen and unheard, see with the eyes of your heart.
Eons ago, I didn't see any evidence for God. But after I was (facing Death) I reached for the unseen and said Lord be with me! And He was...I learned to set aside my intellect and to look for myself. And suddenly, I see God's Fingerprints Every Where!
Think about it. The Lord Created everything and we the branches of the Lord's Vine. All of creation. Nothing made by God can live apart of it's creator. And we know that in the flesh we have been lied to about everything for our whole life. So assume that your intellect is wrong and that God is right.
But it has to be done unseen with no proof. In absolute faith. Proof? There's God's Fingerprints right there! I can't make a Tree! Can you? So it takes a bit of a different perspective.
