Believers will not be condemned or judged as our judgment for sin took place on Calvary's cross (John 3:16-18, Rom 8:1) whereas non-believers will be judged for sins (Rom 6:23). I imagine that believers at the Judgment Seat of Christ will be elated to finally meet Jesus face to face and hear "well done, good and faithful servant" while receiving rewards according to their labour (Mark 9:41, Rev 22:12) . On the other hand, I imagine non-believers will have lots of unjustifiable excuses when the books are opened and their entire life is exposed to them at the Great White Throne Judgment. There will be some "Lord, Lord, have we not prophesied in thy name" and "I never knew you, depart from me, ye that work iniquity".
Therefore it is by the reason one does what one does to whether they will be justified or not and it is
Galatians 3:8Scripture foresaw that God would
justify
the Gentiles by faith, and announced
the gospel in advance to Abraham: “All nations will be blessed through you.”
Galatians 3:11Clearly no one who relies on
the law is
justified before God, because “
the righteous will live by faith.”
Galatians 3:24So
the law was our guardian until Christ came that we might be
justified by faith.
Galatians 5:4You who are trying to be
justified by
the law have been alienated from Christ; you have fallen away from grace.
Ephesians 5:2and walk in
the way of love,
just as Christ loved us and gave himself up for us as a fragrant offering and sacrifice to God.
Romans 15:7Accept one another,
then,
just as Christ accepted you, in order to bring praise to God.
Romans 1:17For in it the righteousness of God is revealed from faith to faith; as it is written, “The just
shall live by faith.”
