Romans 15:13 talks about “May the God of hope,” which is confident expectation, “fill you with all joy and peace in believing.” God is a believer. He has no problem believing. Therefore, neither should we since we are in Him. So in every situation you encounter, He gives you a measure of faith for that situation. He doesn’t just give you one measure of faith that has to last you the whole of your life. I think in every situation you come into you get a measure of faith. So if you have three or four situations going on right now, you might have three or four measures of faith. Why don’t you just put it all together and see what that looks like?
