The ultimate goals of Christianity and Islam couldn't be more different. The goal of Islam is fundamentally submission to Allah: Islam means submission to God, and a Muslim is one who submits. While Christianity teaches that Christians should submit to the Lordship of Jesus Christ, the ultimate aim of Christianity is the knowledge of God: "This is eternal life, that they may know you the one true God and Jesus Christ whom you have sent." (John 17:3) Redemption, reconciliation with God through Jesus Christ, is the necessary stepping stone to attaining the knowledge of God. In fact, "mere forgiveness" without the knowledge of God corresponds to the stage of "a little child" (1 John 2:12-14) Sins are forgiven, but new converts are expected to grow into fathers, "who know Him who has been from the beginning." This intimate knowledge of God, grounded in the Truth, which is Christ Himself, leads to "sincere worship." (John 4:23-24) Christ presumed that true worship is based on genuine knowledge, for "we worship what we know." (John 4:22) False worship, by contrast, is adherence to beliefs and traditions not grounded in the Truth. In the case of Islam, "worship" is submission to an unknowable god called Allah. Indeed, the demand to submit to a god who cannot be known should alert Muslims to the nefarious presence informing Islam. Interestingly, Mohammed himself thought he was demon-possessed after his violent encounter with an "angel of light"-- Gabriel.
