The prophet Habakkuk gets up into his watchtower and strikes the keynote of the gospel: " The just shall live by faith." He gets into the presence of God, and only watches for what He will say. He had not a single thing besides and he says, " If you want to be justified it must be by faith." This did not alter Habakkuk's circumstances, but his soul being occupied with the secret of God was kept at rest.
One who has faith takes God's estimate-does not look for the evidence of his own senses, but says, Let me hear what God says, He must be true. What God says will come into constant collision with what is in myself, but I have to say, "Let God be true and every man a liar."
