Faith is trusting God, even though we can't see Him. And even if we could--the Israelites could see His workings with great drama and yet they still needed faith. I need it every day, even though I have the Bible and am surrounded by many believers, all of whom also have faith.
What am I trusting God for today? There are the resident, baseline things like a) if I die tonight I have faith He will take me to heaven b) the Gospel is applicable for all people, all of the time. c) His providence and care are there for me--He will never break a promise to me. But what active issues and challenges am I consciously trusting God about? Of this I should take regular inventory. There should be a number of things that are engaging my day-to-day trust in Him, and which I am frequently asking Him about. Daily faith is more than passive. It is active. It is a turning-over-to-Him intentionally, of things I would rather try to handle (or worry about) myself. A person of great faith, I think, is a person who is actively, deliberately taking God at His word. "Ok God, you have said it, now do it." This of course, assumes I am accurately interpreting His promises, and not stealing promises made to Israel or the early church and appropriating them to myself just because I like reading them. But there are a great many promises in the New Testament which ARE intended for all believers. These are precious, and the things that energize my faith. What of THOSE am I actively trusting Him for?
