 This is beyond comprehension but a declared truth of the word of God. Peter says we who are saved are the elect by the foreknowledge of God. Jesus knew who he was dying for. He knew who he was going to the cross for. That gives me comfort. That gives me comfort because it means that even before I lived my life, even before I messed up and decided I wasn't worthy of him, he had already decided I was worth it to him. He loved me enough that he was willing to die for me.
