Effective prayer is the fruit of a relationship with God, not a technique for acquiring blessings.
D. A. CarsonThe clichรฉ, God hates the sin but love the sinner, is false on the face of it and should be abandoned. Fourteen times in the first fifty Psalms alone, we are told that God hates the sinner, His wrath is on the liar, and so forth. In the Bible, the wrath of God rests both on the sin (Romans 1:18ff) and on the sinner (John 3:36).
D. A. CarsonDamn all false antitheses to hell, for they generate false gods, they perpetuate idols, they twist and distort our souls, they launch the church into violent pendulum swings who oscillations succeed only in dividing brothers and sisters in Christ
