blameless?

16"For God so loved the world that he gave his only Son, so that everyone who believes in him will not perish but have eternal life. 17God did not send his Son into the world to condemn it, but to save it.
18"There is no judgment awaiting those who trust him. But those who do not trust him have already been judged for not believing in the only Son of God. (John 3:16-18)

When we face God at the final judgment, those who get to remain with him are those who are blameless. Those who are perfect. Right away you might say, “No one is perfect.” There is where you would be wrong.

19For God in all his fullness was pleased to live in Christ, 20and by him God reconciled everything to himself. He made peace with everything in heaven and on earth by means of his blood on the cross. 21This includes you who were once so far away from God. You were his enemies, separated from him by your evil thoughts and actions, 22yet now he has brought you back as his friends. He has done this through his death on the cross in his own human body. As a result, he has brought you into the very presence of God, and you are holy and blameless as you stand before him without a single fault. (Colossians 1:19-23)

Jesus offers to stand in our place. Take our punishment upon himself. We will stand before God perfect.

Now, those who do not trust in Jesus can theoretically be saved. If they can stand before God blameless on their own merit, then they will be able to live in his presence forever. The reality is no person can stand before God perfect. By not trusting in Jesus, he/she has already become the kind of person who cannot want to live with God for eternity. God honors this desire. This is why scripture says, “But those who do not trust him have already been judged for not believing in the only Son of God.”

Unbelievers become their own judge. The sentence is handed down before they even stand before God in judgment. The sentence? Separated from God forever. They get their wish. God is so loving that both believer and unbeliever get exactly what they want. The choice is not made by God. The choice is our own.
