My good friend, I think we might do well to review some basics here.
The prince of this world influences the general character of this world. Jesus Christ is not the prince of this world. See John 16:11.
In his suffering and death on the cross, Christ waged the greatest war of all time and won that very day. Our sovereign God raised Christ from the dead on the third day. Anyone who believes on him will have everlasting life. We serve a mighty God.
Our God gave us free will. With it we can choose either the glory of heaven or the lake of fire.
I would like you to help me, my friend. Can you tell me what language Jesus spoke when he said on the cross “It is finished?” I’m not an expert on these things.
