A simple answer Nick. The Prophet Muhammad pbuh tell you, if you studied his words accurately that Jesus was a Prophet. Therefore he couldn't have the kingdom to which you refer.
That's not a derail Nick, that's a proper counter argument.
If only you would read the Qu'ran accurately and with an open heart. Then you would understand.
Not biting today Seb...even you can see through your half-hearted argument to poke fun at both deities.
Better to realise that Islam is the religion of Esau and it too has a Biblical claim.
But Jesus Christ is offering even you Seb, salvation, but not freely or without a righteous turn around and quickly.
Quickly here means...no one knows the hour or the day...except Almighty God who is in Heaven...but all the signs are saying...'quickly'...and if you think you can argue with a power that can travel the universe as obviously as they can, I would be more mindful of saying the things that might offend them.
