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.- Robert A. Peterson, Hell on Trial: The Case for Eternal Punishment, P&R Publishers, 1995, p.50.

What is meant by calling the writings of Moses and the
Prophets [the] "Old Testament"? Do they not set forth the
covenant of grace? The doctrine of justification by faith: does
not Paul in his Epistle to the Romans prove it from Genesis
(case of Abraham) and from the Psalms (case of David, Ps. 32)?
Where is the doctrine of substitution and the vicarious
sufferings of the messiah set forth more clearly than in
Leviticus and in the 53rd of Isaiah? The term "Old Testament"
leads people to fancy it is an antiquated book; whereas, in
many respects, it is newer than the New Testament, referring
more fully to the age of glory and blessedness on the earth
which is still before us.-Adolph Saphir (1831-1891), Christ and Israel, London: Morgan and Scott, 1911, p. 140
