It 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.
Timothy KellerBoth men and women today see marriage not as a way of creating character and community but as a way to reach personal life goals. They are looking for a marriage partner who will 'fulfill their emotional, sexual, and spiritual desires.' And that creates an extreme idealism that in turn leads to a deep pessimism that you will ever find the right person to marry.
Timothy KellerWhen love of one's people becomes an absolute, it turns into racism. When love of equality turns into a supreme thing, it can result in hatred and violence toward anyone who has led a privileged life. It is the settled tendency of human societies to turn good political causes into counterfeit gods.
