In order to answer this question, one must carefully consider what religion is and the role it plays on the world scene.
We must also go into Scripture to see if religion was something that Jehovah God wanted established on the earth.
Why Was Jesus Sent?
According to Scripture, Jesus was not sent to establish a new religion on the earth bearing an offshoot of his title: Christ, that is, Christianity.
For Jesus to do that would be taking it upon himself to do his will rather than the will of his Father; and Jesus would never do that. If Jesus was sent to establish a religion on earth – and he wasn't – he would have insisted that it be something that would reflect the His Father – not himself.
Jesus was sent by God to the earth to offer himself up as a sacrifice in all of mankind's behalf; to restore what Adam lost for is all: Eternal life and alienation from our Creator.
In doing this Jehovah gave Jesus a message to bring with him – Good tidings – that essentially state that all who believe what God told him would not perish, but have everlasting life. That the word's Jesus spoke were God's words and any believing these words would lead them to life. Jehovah is the ultimate giver of life.
This is no different from what God told Adam in the Garden of Eden; that Adam's continued existence depended upon him feeding from God's Word as presented by the fruit on the Tree of the Knowledge of Good and Bad.
Even Jesus told Satan:
Man does not live on bread alone, but on every word that comes from the mouth of God. (Matthew 4:4)
Adam had the other trees in the Garden to physically nourish himself, but they alone would not sustain him. It was essential that he feed from the words that came out of the mouth of God in order to live,
God sent Jesus as his representative and bearer of his word. Therefore, any listening and believing on to him – The Word of God – would have life.
So, Jesus was not sent to establish a religion called Christianity. Rather, he was sent by God to present to them the words that God gave him to deliver. Those believing in these words would assemble themselves into a simple Brotherhood. They did not establish an authoritarian system like what we see today in the Church-systems. In fact, it was men who coined the term "Christianity" and made it into what it is today.
Is There a True Religion?
Since Jesus did not establish any religion on earth, it only follows that there is no true religion. This writer believes that all religion on earth is counterfeit and false. If there is no true religion on earth, what is there?
The truth in Jesus. The bearer of God's word which is Truth.
Jesus said at John 14:6:
I am the way and the truth and the life. No one comes to the Father except through me.
It is Jesus – and no human or human agency, that is the bearer of the truth. He bears God's Words! Jesus is also the way. The way to what?
Recall in the Book of Genesis where Adam and Eve were put out of the Garden of Eden. What was it that was guarded? The way back to the Tree of Life. A tree that Adam free partook of. (Genesis 3:24)
Jesus is the only way back to that Tree of Life. The Tree of Life is Jehovah God. The fruit is his words. That was what would sustain Adam indefinitely if he had only listen to God's word (fruit) rather than listening to the fruit (words) of the Serpent through his wife Eve.
Jesus is the gateway to the Tree of Life. That is why he could say: No one comes to the Father except through me. (John 14:6)
At the transfiguration in Luke 9:35, who was it that Jehovah said we were to listen to?
And a voice came out of the cloud, saying: “This is my Son, the one that has been chosen. Listen to him.
If, now, the good news we declare is in fact veiled, it is veiled among those who are perishing, among whom the god of this system of things has blinded the minds of the unbelievers, that the illumination of the glorious good news about the Christ, who is the image of God, might not shine through. (2 Cor 4:3-4)
