John 8:19, “If you knew Me, you would know My Father also.”
Thus, the only way to know God is through His Son, Jesus Christ. Anything that is not sanctioned by Christ, therefore, is of the Devil. If this sounds too harsh or drastic, that is a worldly mind. When our minds are set in the flesh, of course this is drastic! The world and the flesh want to set its own way. When the mind is set on the Spirit, however, we accept this reality (cf. Romans 8:5-8). Thus, Allah is not God, for Islam rejects His Son. “Allah” is “God” translated into Arabic, but this is merely linguistic. Conceptually, Allah is not the Father of Jesus Christ; therefore, Muslims do not know God. Similarly, Jehovah’s Witnesses deny Christ as the Son of God; therefore, they do not know God. Jesus Christ is our only access to God, whom God has graciously given to us. If you desire to know God—if you desire salvation—you need to know Jesus Christ. There is no other way (cf. John 14:6-9).
