Did you get that? When we hold on, when our faith is evident, when we are proving to all the world, to ourselves and to the unseen realm we are believing in God and He is it for us, we give something to God, the one thing that makes Him happy! We can make the God of the Universe joyful! We can make the God of the Universe Proud!
Thinking on this makes me want to hold on even more during rough times. I can actually make my Father in Heaven happy. Think on that. Wow.
This is really the only thing we can give Him, the one thing that is genuine. And I guess when we give money or give other stuff in His name it gets back to this too. When we give or do anything in His name, if we do it out of belief, out of that belief that is way down deep, it makes God happy.
This is when "doing" is faith. Read James 2.
