No Original Sin
As we all know several Christians believe in the doctrine of original sin, that all humans are born with sin, and that we are basically stained from birth. Much like many other Christian beliefs, the doctrine of original sin has no real basis within the Bible, and is merely an invention by the Church and Christians, much like the Trinity, and divinity of Jesus Christ.
Jesus himself never taught such a thing as original sin, rather Jesus explicitly taught the opposite of original sin! When we go read the Gospel of Matthew 18 verses 1-4 we read this interesting incident:
At the same time came the disciples unto Jesus, saying, Who is the greatest in the kingdom of heaven? And Jesus called a little child unto him, and set him in the midst of them, And said, Verily I say unto you, Except ye be converted, and become as little children, ye shall not enter into the kingdom of heaven. Whosoever therefore shall humble himself as this little child, the same is greatest in the kingdom of heaven.
So notice what happens here, the disciples ask Jesus who will be the greatest in the kingdom of heaven, and Jesus uses a child as an example, now ask yourself this, why would Jesus use a stained sinner as an example of the greatest in heaven! Christians believe that no one with sin can enter heaven, as sin cannot be around God, so how could Jesus use an example of a SINNER?!
Obviously Jesus did not believe children are born with sin, and it makes perfect sense as to why he would use a child as an example, because as we all know children are innocent people, and indeed the greatest one in heaven will have to be like a child, innocent, humble, and pure. Original sin says the opposite, original sin does not even spare the young children as it teaches that ALL humans are BORN with sins, naturally this includes babies and children!
So if Jesus believed in original sin, that all humans are born with sin, then how could use a sinner as an example of the greatest person in heaven, can you compare a sinner with the greatest in heaven, does that make any sense?
And Allah Knows Best!
