Isa 43:11 (NIV) "I, even I, am the Lord, and apart from me there is NO savior."
Hos 13:4 (KJV) "Yet I am the Lord thy God... and thou shalt know no god but me: for there is NO saviour beside me."
John 14:6 (NIV) "I am the way and the truth and the life. No one comes to the Father except through ME."
Mohammed, Buddha, Krishna, and others taught a way to God, some truth about God, and gave instructions on how to live life. These religions did not originally claim to be exclusively true, just better than competing brands. Christianity, however, is unique. It claims "revelation" truth: that God has once and for all "expressed Himself". Jesus Christ is what God wanted to say.
John 14:6 (Phi) "I myself am the way and the truth and the life. No one approaches the Father except through ME."
Acts 4:12 (NIV) "Salvation is found in no one else, for there is no other name under heaven given to men by which we must be saved."
