So neither he who plants, nor he who waters is anything, but only God, who makes things grow.
I'll tell you I find this passage a real relief. It's not up to me to make things happens, I just have to either plant the seed or water it. Especially helpful to remember when you're involved in something like Alpha. So Lord just give me the obedience to do what you put in front of me and the faith to trust you to make things happen.
