Christianity is not a religion, Christianity is the truth; let me explain.
For hundreds of years the greatest minds throughout the world from Greek Philosopher Socrates to Egyptian King Pharaoh, debated whether the world was FLAT? ROUND? or ENDLESS? Every country had a different belief. But worst, People were labeled heretics, then prosecuted and died for their beliefs if they denied the theory that the world was flat.
There were many theories about the earth but ONLY 1 TRUTH: The Earth is Round.
Think of these past belief systems about the shape of the world as current belief systems surrounding religion. Think about the people who believed the world was flat or endless as the forefathers of the current generation who believe in BUDDHISM, HINDUISM, or SATANISM just to name a few.
Think about this, many religions say they worship God but there is ONLY 1 TRUTH: Christianity; The Belief that Jesus Christ is Lord.
In summation, there will always be different versions to a story but only 1 Truth; everything else is a lie. Likewise there will always be many religions but only 1 Truth; everything else is a lie. Jesus Christ said " I am the way, the truth and the light. The only way to the Father God is through Me." John 14:6
