>>So then, nothing really matters, as you said.
Everything matters. If you seek after God, then God chose you. Your theology does not matter to him. Only HIS theology matters to him.
>>Comforting, that.
It should be, but I sense that you want to be the master of your destiny and you feel that God needs to obey your wishes to choose him and then he needs to reward you for your efforts, even though he told you that they are sewage to him. Take comfort in the fact that God is a better God than you are, even though you hate that.
The great thing about God is that He willed NOT to be the only will in the Universe. The geat thing is that He willed beings who could do as they will. That's what makes love possible.
If we were acting out predestined scripts such that our choices meant nothing, there would be no love (unless you think you could, for example, get love from a sexbot.)
If we had no choices, it would be nothing but gratuitous sadism for God to use any imperative verb.
"Repent and believe the Good News", "Love the Lord your God," "Choose Life"--- glory to God, He means exactly that.
