Everything that a man leans upon but God will be a dart which will certainly pierce his heart through and through. He who leans only upon Christ lives the highest, choicest, safest and sweetest life.
— Thomas Brooks
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
