All Religions Are True?

And there is salvation in no one else, for there is no other name under heaven given among men by which we must be saved." (Acts 4:12 ESV)

All religions are true. God can be reached by different religions. Many rivers flow by many ways but they fall into the sea. They all are one. - Sri Ramakrishna (1836-02-18 to 1886-08-16)

Let say there is a big problem that will cause the end of the world. Let say there are found 10 ways that will effectively solve this problem and the world will not end. Nine of these ways do not require the death of any living thing. The tenth way requires the death of your only son. What will you do? Will you offer up your son and say, "Better let him die and save the world, just in case the other nine ways fail" or would you say, "Why don't we try the nine other ways first?"

If God knew of nine effective ways to save the world without the death of any living thing, why would He send His only begotten Son to die on the cross? God would have committed a blunder that even a normal, rational human does not do.

Many people like to say that all religions are true, but may I submit to you that this statement is a lie. If the Bible is true, then all the non-Bible based religions are false. If one or some or all non-Bible based religions are true, then Christianity is false. So it will never be "all religions are true".

Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me. (John 14:6 KJV)

"Turn to me and be saved, all the ends of the earth! For I am God, and there is no other. (Isaiah 45:22 ESV)
