Some find that a great comfort and others find it something to be fought against. In any case, His sheep hear His voice and follow Him.
I don’t find God in control of everything to be frightening at all. It is sort of comforting, to be honest with you.
I do worry about those He didn’t “foreknow (and) predestinate”, but that’s not my pay grade, and the truth is that I’d worry about the lost in any case, because of God’s foreknowledge. On the other hand, all have sinned and fall short of the glory of God, and the wages of sin is death, but the gift of God is eternal life through Jesus Christ our Lord.
So, where are we left? The lost are the lost in any case. My proclamation role is the same in any case. My impact is exactly what God has determined and/or foreseen it will be; no more and no less.
As for Kosta50? He’ll come around or he won’t. He’s a sheep or he’s a goat. God knows.
