The Body of Christ is also called a nation, a new nation through Christ, citizens and heirs who belong to the Kingdom of God, being recipients of God's mercy. But you are a chosen people, a royal priesthood, a holy nation, a people belonging to God, that you may declare the praises of him who called you out of darkness into his wonderful light. The return of the Lord will usher in judgement. Judgement of moral character revealed by charitable deeds are to be commended but not a condition for salvation, for it is not of works. Jesus is not teaching that good works form the basis of salvation , although works of a Christian will be judged.
Good works come from a grateful heart.
Good deeds are the fruit of the righteous and not the basis for their salvation. The right hand throughout God's Word has always symbolised blessing while the left hand has always symbolised as being cursed. The sheep and goats are divided. On the right to inherit the Kingdom, on the left to everlasting fire. He will separate as the weeds and wheat are separated at the harvest.
