Charles Spurgeon Commentary Habakkuk 2:4

"Behold, his soul is puffed up, it is not upright in him; but the righteous shall live by his faith." — Habakkuk 2:4 (ASV)

This grand text was quoted by Paul when he wrote his Epistles to the Romans, the Galatians, and the Hebrews. It proves that Old Testament saints understood New Testament life. David and Abraham lived by faith, even as Paul and Peter and the other apostles did.
