Jesus’ preaching about hell is part of His gracious ministry to a lost world. It is His way of showing unbelievers their need of Him. They, in turn, inevitably make one of two responses. Some display ingratitude for His warnings and reject Him. Others, however, gratefully own Him as the One who alone can rescue them. Instead of experiencing the wrath their sins deserve, they will taste the sweet victory won by His death and resurrection.
