A christian told me God can transform to be a Devil because - With God nothing is impossible" is that what majority of christian believed?

That so called christian is not servant of GOD but servant of devil

What the majority of Christians believe does not describe the truth. There are many who call Jesus their Lord, and that is how most statistics experts say who belongs or follows a certain belief.

However, the question of whether or not God can transform into the Devil could only be answered with a study of the God-inspired scriptures. It says;

Job 34:10

10 So listen to me, you men of understanding:

It is unthinkable for the true God to act wickedly,

For the Almighty to do wrong!

Mark 10: 17-18

As he was going on his way, a man ran up and fell on his knees before him and put the question to him: “Good Teacher, what must I do to inherit everlasting life?” 18 Jesus said to him: “Why do you call me good? Nobody is good except one, God.

There is your answer. The word "Devil" means "slanderer." Can God transform into a Devil?

Christian scripture says that Jesus removed the figurehead of the evil world administration known allegorically as the 'Serpent.' We know him better as the 'devil' or 'Satan.' Jesus did this by becoming the 'Serpent upon the Staff' Himself. Medical doctors still use this today as the symbol of their profession. This symbol originates with Torah, (Numbers 21), during a narrative in which the children of Israel were being attacked by venomous snakes and Moses was instructed to elevate a bronze image of a serpent coiled around a wooden staff, and anyone who had been bitten and gazed steadily upon the serpent would live.

While we could view this on many levels, the level most relatable to 'modern' people would be the explanation that this emblem caused the people to stop panicking after first being bitten. Their panic likely resulted in them being bitten numerous more times and dying. The venom was not deadly unless their collective panic created this much worse situation. Jesus represents the emblem of the potentially deadly poison of 'sin.' Scripture indicates that in order for Him to remove the previous evil world administration, He had to actually 'become sin,' (2 Corinthians 5:21).

We think of 'sin' only as violations of divine Law, yet Jesus did not commit any of those. How could He have 'become sin?' We forget that 'sin' is a legal term of divine Torah. No term of the eternal divine Law can ever be altered. However, God did something extremely ingenious and unexpected. He 'double-defined' terms within His own Law. So 'sin' must continue forever to be a reference to the state we end up in after we violate any of the divine ordinances, but it now has an alternative definition. 'Sin' is now also the state a perfectly righteous man finds Himself in after surrendering all of His divine rewards and pleasures, (known as the 'ecstasies'), in payment of the debts of all people who willingly surrender their 'panic' at having been bitten by the notorious 'Serpent' of evil which has destroyed so many others by inspiring them to treat others unequally and unfairly and then falling under natural judgment for it. God's Law cannot be altered or avoided. However, now God has two options for applying His Law to us as individuals. He may either use the original definition for 'sin' for which there is no existing remedy, or He may use the alternate definition which gives us the opportunity to stop panicking and live. That choice is God's alone. He is under no obligation to use one or the other. When He decides to use the one that liberates us, that is called 'grace.' Our role in it is to gaze upon the example of the new 'Serpent' and stop thinking only of ourselves in desperate, selfish fear, looking to Him who loved others with equal love even though He was never under any obligation to do so. Divine Law is based in this:

'Love all others exactly as you love yourself.'

When we do this instead, God looks with Self-recognition upon us and we 'live,' since He is the Author of life.

God's decision to 'take the devil's place' has created a new world administration while proving the very point you are inquiring about. With God, all things are truly possible.

Why would god tell you that you can transform to be a sevil? No Christian would say that. Watch for false words...

just because something is possible doesn't mean its going to happen

When Christians listen to the guy in the box instead of the word of God...weird things happen

only God knows

God cannot be with evil. Why would he become evil? He wouldn't.
