The gospel shows us that our spiritual problem lies not only in failing to obey God, but also in relying on our obedience to make us fully acceptable to God, ourselves and others. Every kind of character flaw comes from this natural impulse to be our own saviour through our own performance and achievement. On the one hand, proud and disdainful personalities come from basing your identity on your performance and thinking you are succeeding. But on the other hand, discouraged and self loathing personalities also come from basing your identity on your performance and thinking you are failing.
Timothy KellerThe church does not simply have a missions department; it should wholly exist to be a mission.
Timothy KellerLook at Jesus Christ. Every time he was in trouble he used the Word of God. When he was tempted he used the Word. When he was suffering on the cross he used the Word.
Timothy KellerGod is so committed to your ultimate joy that he was willing to plunge into the greatest depths of suffering himself for you.
Timothy KellerIf you aren't constantly astonished at God's grace in your solitude, there's no way it can happen in public.
Timothy KellerIt is inaccurate to think the gospel is what saves non-Christians, and then Christians mature by trying hard to live according to biblical principles. It is more accurate to say that we are saved by believing the gospel, and then we are transformed in every part of our minds, hearts, and lives by believing the gospel more and more deeply as life goes on.
