OGK

There are some things that only God knows (OGK) until the time He chooses to reveal them. The Son of God was pleased to die for the sons of men whom He chose in Him before the foundation of the world. Election is backstory. It is what we find out later. At the point of conversion all we know is that we decided to follow. We wanted to believe. What only God knew until He chose to reveal it was that He first chose us. John15:6, "you did not choose Me but I chose you."
