There are really only two religions in the world. One of Cain and the other of Abel. One of Ishmael and the other of Isaac. One of Esau and the other of Jacob. One of law and the other of promise. One of Mount Sinai and the other of Mount Calvary. One condemns, the other finds no fault. One leads to bondage, the other to freedom. One tendeth to death, the other to life. One of weakness, the other of power. One of merit, the other of mercy. One of the weakness of the letter, the other of the power of the Spirit.
