The purpose of Chirst into this world is to preach the kingdom of God and to call the sheep of God so that they will be saved and have a chance of salvation.
He purchase it with His own Blood.
Everything to God has timing and He is not rushing up.
Christ preach in the age of 30-33, Chirst lived a normal life below 30.
He's a carpenter and a good example of a responsible and obedient child.
ANd lastly, He is not a Magician, He is a God that can Do what is seems impossible to us.
And Magic we know today are tricks.
Peace!
