Seems to me that those who choose to reject absolute truth are in fact rejecting God. It will not end well for them.
The kings of the earth set themselves, and the rulers take counsel together, against the LORD, and against his anointed, [saying], Let us break their bands asunder, and cast away their cords from us.
He that sitteth in the heavens shall laugh: the Lord shall have them in derision.
Then shall he speak unto them in his wrath, and vex them in his sore displeasure. – Psalms 2:1-5
Seems that way to me, too, dearest sister in Christ!
Yet it is because they reject absolute truth that they cannot see the peril they face, in the now and the hereafter both. For God is Truth, and He is a Just God. (Indeed, science itself depends on this understanding.)
Such folk laugh at us for saying such things. But it seems to me, God always has the last laugh in such matters. And so, as you say, quite possibly "it will not end well for them."
Thank you so very much for excerpting Psalms 2:1–5. It is the perfect cite on this question. And thank you so very much for writing, dearest sister in Christ!
