Nor is there salvation in any other, for there is no other name under heaven given among men by which we must be saved. (Acts 4:12)
John 10:30; 14:6
No religion other than Christianity has a book like the Bible that tells us about the origin of everything, and who we are, where we came from, what our problem is (sin), and what the solution to our sin problem is. No other religion has a Savior who is alive (He rose from the dead). All other religions require people to do something to work out their future—only Christianity has the solution that we can’t save ourselves, only God can do it. So how can we know if other religions aren’t true? Well, if they don’t agree with the Bible they are not true! There are two main tests I want you to use though.
First of all, any religion that claims to be true must believe that Jesus is God! Remember, Jesus Himself told us that He and the Father are one. Many religions talk about God a lot . . . but if they don’t believe in Jesus and that He is God, and they don’t believe that Jesus’ death on the cross and His Resurrection results in our sin being forgiven if we will receive it, then it is not the truth! The other test is to find out if they believe that salvation is given to those who trust in Jesus . There is nothing you can do to save yourself. We could never do enough good works to get us to heaven, but Jesus did it when He died for us! Jesus Christ is the way, the truth, and the life.
