While the difference between a bad sermon and a good sermon is mainly the responsibility of the preacher, the difference between good preaching and great preaching lies mainly in the work of the Holy Spirit. . . . We should do the work it takes to make our communication good and leave it up to God how and how often he makes it great for the listener.
Timothy KellerReligion operates on the principle 'I obey-therefore I am accepted by God.' But the operating principle of the gospel is 'I am accepted by God through what Christ has done-therefore I obey.'
Timothy KellerThe Gospel is news of what God has done to reach us. It is not advice about what we must do to reach God.
