To the degree you experience God's love towards you - seeing you as beautiful and radiant - to that degree sex won't ruin your life.
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 KellerElder brothers obey God to get things. They don't obey God to get God himself — in order to resemble him, love him, know him, and delight him.
Timothy KellerWhile Christianity was able to agree with pagan writers that inordinate attachment to earthly goods can lead to unnecessary pain and grief, it also taught that the answer to this was not to love things less but to love God more than anything else. Only when our greatest love is God, a love that we cannot lose even in death, can we face all things with peace. Grief was not to be eliminated but seasoned and buoyed up with love and hope.
