"That's the problem, of course. Everyone's religion is the true religion. I've never met anyone who thought that their religion was false.It is always someone else's religion that is the false one.".. " This means everlasting life, their taking in knowledge of you, the only true God, and of the one whom you sent forth, Jesus Christ. 4 I have glorified you on the earth, having finished the work you have given me to do. 5 So now you, Father, glorify me alongside yourself with the glory that I had alongside you before the world was. 6 “I have made your name manifest to the men you gave me out of the world."John 17:3-6. It is not really that hard.Just identify the One Jesus was praying to in this passage "the only true God",the One whose name Jesus made known[see John 17:6],and then ask yourself 'Which is the only footstep followers of Jesus who also worship the Father & make his name known?'
