Morality will keep you out of jail, but only the blood of Jesus will keep you out of hell.
— C. H. Spurgeon
The four Gospels all had the same purpose: to point out Christ. The first three Gospels show his body, so to speak, but John shows his soul. For this reason I usually say that this Gospel is a key to understanding the rest; for whoever understands the power of Christ strikingly pictured here will then profit by reading what the others tell about the Redeemer who appeared.
— John Calvin
