Wrong is subjective because “evidence” is subjective. The message you are delivering is that there is no sense in believing in God because he ain’t comin’ back.
My problem is with any Christian that chooses to call those who believe Jesus may return in their lifetime as members of a cult.
Luke 21:28
And when these things BEGIN to come to pass, then look up, and lift up your heads; for your redemption draweth nigh.
