I have no doubt that the Jews confused the two (as you do) but the reason that no other Gospel has it but Matthew is to show the Christian that there is a difference.
Nope, there must be a difference even though the SCRIPTURE does not declare one!!!
Ofcourse it does, it defines Kingdom of God as a spiritual kingdom and the Kingdom of Heaven is a literal physical one as depicted in Daniel.
But for someone who thinks Satan is bound today, (but not really), I know this is a little too deep.
Your dispensationalism has you holding to physical hopes which will disappoint.
My Dispensationlism is what makes sense of Scripture which you twist out of recognition with your context dropping and spiritualizing (2Pet.3:16)
The Jews could not see the spiritual applications and truth of their messiah, and you cannot see them of His promises. When you die disappointed, ask Him why He did not come back before you died. He will tell you He did!
First, If I die before He returns I will not die disappointed because the event will happen (Rev.19).
And when we are standing at the Judgement seat of Christ (1Cor.3:13) you can explain to Him why you rejected clear scripture for illusions and delusions.
Ofcourse it does, it defines Kingdom of God as a spiritual kingdom and the Kingdom of Heaven is a literal physical one as depicted in Daniel.
Amen!
Maranatha!
