'Justifies' in the Bible
Then the Rabshakeh said to them, “Say to Hezekiah, ‘Thus says the great king, the king of Assyria, “What is [the reason for] this confidence that you have?
He who justifies the wicked, and he who condemns the righteousAre both repulsive to the Lord.
It was to demonstrate His righteousness at the present time, so that He would be just and the One who justifies those who have faith in Jesus [and rely confidently on Him as Savior].
But to the one who does not work [that is, the one who does not try to earn his salvation by doing good], but believes and completely trusts in Him who justifies the ungodly, his faith is credited to him as righteousness (right standing with God).
Who will bring any charge against God’s elect (His chosen ones)? It is God who justifies us [declaring us blameless and putting us in a right relationship with Himself].
