Christ was not a political activist, nor are his real followers (the only people who should be labeled "Christian").
On the contrary, he was a Jewish zealot determined to free Israel from Roman rule. Hence he said "I came not to bring peace, but to bring a sword". According to the Gospel of Luke, sell your cloak and buy a sword is an instruction by Jesus to his disciples.
Both Jesus and Paul were wrong about the time of the coming of God but you think you know? Paul said it would come as a thief in the night.If the OT is from God/true (as I'm confident it is), then soon we will SEE a Russian ("great power to REMOTE north") led invasion of Israel.
The OT reveals the outcome of this invasion. The invaders will be annihilated.
This event will cause many current non-believers to become believers in the God revealed in the Bible.
No point in arguing about it ..... just wait and see.
