I’m always reminded of C.S. Lewis’ book The Last Battle when I see this question. I think when we see Jesus, some will instantly love Him, and some will immediately hate Him.
It’s terribly sad.
When you’ve been searching for God all your life, wanting to know Him and let Him be the Lord of your life, and you finally see Him in the flesh, Love personified, you will immediately love Him and know Him. Even those who have never heard of Jesus, if they’ve been searching for the Truth, will know the Truth when they see Him.
But for those who have spent their entire lives rejecting God, running from Him, ignoring every whisper of His spirit, giving themselves entirely over to appetites of the flesh…when they see God, they can easily reject every loving overture and choose themselves. They would rather be a king over their own life than bend their knees to the King of Kings.
And so God lets them be a king over themselves, a prisoner of the flesh, unable to understand or accept His divine mercy and grace.
That’s why it’s so important to know God and love Him now, and to learn to deny ourselves and seek His kingdom, and not wait until the moment of death to make that final choice.
St. Joseph, pray for us that we are granted the grace of final perseverance, and like St. Paul, that we can run the race, without fainting, until the end, looking unto Jesus the author and finisher of our faith.
