Islam worships the god of Abraham, same as Jews and Christians....
But for christians, the only path to god is through jesus. That's the christian teaching. The other two still contain the vestiges of filthy tribalism and worship an ancient diety that may or may not be the god of christians. Jesus is the proof in pudding. The body of christ, the bread of heaven, the pudding of the savior. You know the drill.
We believe in one Lord, Jesus Christ,
the only Son of God,
eternally begotten of the Father,
God from God, Light from Light,
true God from true God,
begotten, not made,
of one Being with the Father.
Through him all things were made.
For us and for our salvation
he came down from heaven:
by the power of the Holy Spirit
he became incarnate from the Virgin Mary,
and was made man.
For our sake he was crucified under Pontius Pilate;
he suffered death and was buried.
On the third day he rose again
in accordance with the Scriptures;
he ascended into heaven
and is seated at the right hand of the Father.
He will come again in glory to judge the living and the dead,
and his kingdom will have no end.
