A faith without some doubts is like a human body with no antobodies in it. People who blithely go through life too busy or indifferent to ask the hard questions about why they believe as they do will find themselves defenseless against either the experience of tragedy or the probing questions of a smart skeptic. A person's faith can collapse almost overnight if she failed over the years to listen patiently to her own doubts, which should only be discarded after long reflection.
Timothy KellerIf you come from insignificance and when you die you return to insignificance, then nothing is significant now.
Timothy KellerFor indeed, grace is the key to it all. It is not our lavish good deeds that procure salvation, but God's lavish love and mercy. That is why the poor are as acceptable before God as the rich. It is the generosity of God, the freeness of his salvation, that lays the foundation for the society of justice for all. Even in the seemingly boring rules and regulations of tabernacle rituals, we see that God cares about the poor, that his laws make provision for the disadvantaged. God's concern for justice permeated every part of Israel's life. It should also permeate our lives.
Timothy KellerFaith is not opposed to reason, but it is sometimes opposed to feelings and appearances.
Timothy KellerThe 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.
