Unless we believe the gospel, we will be driven in all we do-whether obeying or disobeying-by pride ('self-love') or fear ('of damnation'). Apart from 'grateful remembering' of the gospel, all good works are done then for sinful motives. Mere moral effort may restrain the heart, but does not truly change the heart. Moral effort merely 'jury rigs' the evil of the heart to produce moral behavior out of self-interest. It is only a matter of time before such a thin tissue collapses.
Timothy KellerMost people in the world believe that if there is a God, you relate to God by being good. Most religions are based on that principle, though there are a million different variations on it...But they all have the same logic: If I perform, if I obey, Iโm accepted. The gospel of Jesus is not only different from that but diametrically opposed to it: Iโm fully accepted in Jesus Christ, and therefore I obey.
Timothy KellerOnly if you are part of a community of believers seeking to resemble, serve, and love Jesus will you ever get to know him and grow into his likeness.
Timothy KellerBy praying with friends, you will be able to hear and see facets of Jesus that you have not yet perceived.
Timothy KellerChristianity offers not merely a consolation but a restoration - not just of the life we had but of the life we always wanted but never achieved. And because the joy will be even greater for all that evil, this means the final defeat of all those forces that would have destroyed the purpose of God in creation, namely, to live with his people in glory and delight forever.
Timothy KellerRemember that according to the Bible, the heart is not primarily the emotions but rather the seat of our fundamental commitments and trusts, and therefore it is the control center of the whole life. So to preach to the heart means to go right for the commanding commitments of people's lives that drive their desires, thinking, feeling, and action.
Timothy KellerLove without truth is sentimentality; it supports and affirms us but keeps us in denial about our flaws. Truth without love is harshness; it gives us information but in such a way that we cannot really hear it. God's saving love in Christ, however, is marked by both radical truthfulness about who we are and yet also radical, unconditional commitment to us. The merciful commitment strengthens us to see the truth about ourselves and repent. The conviction and repentance moves us to cling to and rest in God's mercy and grace.
