1 Timothy 2:4, where it states God "desires all people to be saved and to come to a knowledge of the truth".
Yet before conception CHOOSES who will not be saved ?
Absolutely! According to the purposes He has predetermined.
Rom 9:21 Hath not the potter power over the clay, of the same lump to make one vessel unto honour, and another unto dishonour?
Of course He does.
Some will be saved in this age to serve in Jesus's global government. Every single minister, king and priest have been chosen.
The rest haven't. They will be tried, judged and sentenced to go to the Lake of fire as John called it.
Yet Peter said, The Lord is not slack concerning his promise, as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance.
And as you quoted, God "desires all people to be saved and to come to a knowledge of the truth".
Thus will be in a future age hey. This is absolutely amazing. I get excited when I meditate on this being fulfilled. The return of every prodigal angel along with ALL the judged humans. Yay!!!
