Rejoicing and repentance must go together. Repentance without rejoicing will lead to despair. Rejoicing without repentance is shallow and will only provide passing inspiration instead of deep change.
Timothy KellerPride is the carbon-monoxide of Sin. It silently and slowly kills you without you even knowing.
Timothy KellerEvery one of our sinful actions has a suicidal power on the faculties that put that action forth. When you sin with the mind, that sin shrivels the rationality. When you sin with the heart or the emotions, that sin shrivels the emotions. When you sin with the will, that sin destroys and dissolves your willpower and your self-control. Sin is the suicidal action of the self against itself. Sin destroys freedom because sin is an enslaving power.
Timothy KellerWithin this Christian vision for marriage, here's what it means to fall in love. It is to look at another person and get a glimpse of the person God is creating, and to say, "I see who God is making you, and it excites me! I want to be part of that. I want to partner with you and God in the journey you are taking to his throne."
