Just because you cannot realize your highest aspirations in work does not mean you have chosen wrongly, or are not called to your profession, or that you should spend your life looking for the perfect career that is devoid of frustration. ... You should expect to be regularly frustrated in your work even though you may be in exactly the right vocation.
Timothy KellerMost apologetic books are really written for Christians, even the ones that purport to be written for non-believers.
Timothy Keller[T]he main problem in life is sin, and the only solution is God and his grace. The alternative to this view is to identify something besides sin as the main problem with the world and something besides God as the main remedy. That demonizes something that is not completely bad, and makes an idol out of something that cannot be the ultimate good.
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, Iām accepted. The gospel of Jesus is not only different from that but diametrically opposed to it: Iām fully accepted in Jesus Christ, and therefore I obey.
Timothy KellerThe early church was strikingly different from the culture around it in this way - the pagan society was stingy with its money and promiscuous with its body. A pagan gave nobody their money and practically gave everybody their body. And the Christians came along and gave practically nobody their body and they gave practically everybody their money.
