If we live we live for the Lord, and if we die we die for the Lord. So whether we live or die, we belong to the Lord. For this very reason, Christ died and returned to life so that he might be the Lord of both the dead and the living.
You then, why do you judge your brother or your sister ? Or why do you treat them with content? For we shall all stand before God's judgement seat. It is written...
'As surely as I live,' says the Lord,
every knee will bow before me;
every tongue will acknowledge God. (NIV)
So then, each of us will give an account of ourselves to God.
Therefore let us stop passing judgement on one another.
As every knee shall bow so everyone will confess that Jesus Christ is Lord, even non believer's but it will be to late for them to be with the father if they don't confess Jesus Christ is Lord when they live.
Everyone's knee will bow but for those that did not believe there will be no salvation.
