Three steps toward perfect Justice.

Am I ready for the Justice of God?

"Behold, My Servant, whom I uphold; My chosen one in whom My soul delights. I have put My Spirit upon Him; He will bring forth justice to the nations. "He will not cry out or raise His voice, Nor make His voice heard in the street. "A bruised reed He will not break And a dimly burning wick He will not extinguish; He will faithfully bring forth justice. "He will not be disheartened or crushed Until He has established justice in the earth; And the coastlands will wait expectantly for His law."
(Isa 42:1-4 NASB)

• Step 1 in perfect justice: let he who would be human, identify with the guilty.

...and they were being baptized by [John the
Baptist] in the Jordan River, as they confessed their sins. 

(Mat 3:6 NASB)

Then Jesus *arrived from Galilee at the Jordan coming to John, to be baptized by him. But John tried to prevent Him, saying, "I have need to be baptized by You, and do You come to me?" But Jesus answering said to him, "Permit it at this time; for in this way it is fitting for us to fulfill all [justice]." Then he *permitted Him. After being baptized, Jesus came up immediately from the water; and behold, the heavens were opened, and he saw the Spirit of God descending as a dove and lighting on Him, and behold, a voice out of the heavens said, "This is My beloved Son, in whom I am well-pleased." (Mat 3:13-17 NASB)

• Step 2: let God define the law of the just human.

"You have heard that it was said, 'AN EYE FOR AN EYE, AND A TOOTH FOR A TOOTH.' "But I say to you, do not resist an evil person; but whoever slaps you on your right cheek, turn the other to him also. "If anyone wants to sue you and take your shirt, let him have your coat also. "Whoever forces you to go one mile, go with him two. "Give to him who asks of you, and do not turn away from him who wants to borrow from you. "You have heard that it was said, 'YOU SHALL LOVE YOUR NEIGHBOR and hate your enemy.' "But I say to you, love your enemies and pray for those who persecute you, so that you may be sons of your Father who is in heaven; for He causes His sun to rise on the evil and the good, and sends rain on the righteous and the unrighteous. "For if you love those who love you, what reward do you have? Do not even the tax collectors do the same? "If you greet only your brothers, what more are you doing than others? Do not even the Gentiles do the same? "Therefore you are to be perfect, as your heavenly Father is perfect. 

(Mat 5:38-48 NASB) 

• Step 3 Allow  God to be the one who weighs the human in the scales of perfect justice.

"Do not judge so that you will not be judged. "For in the way you judge, you will be judged; and by your standard of measure, it will be measured to you. 

(Mat 7:1-2 NASB)

Bless those who persecute you; bless and do not curse. Rejoice with those who rejoice, and weep with those who weep. Be of the same mind toward one another; do not be haughty in mind, but associate with the lowly. Do not be wise in your own estimation. Never pay back evil for evil to anyone. Respect what is right in the sight of all men. If possible, so far as it depends on you, be at peace with all men. Never take your own revenge, beloved, but leave room for the wrath of God, for it is written, "VENGEANCE IS MINE, I WILL REPAY," says the Lord. "BUT IF YOUR ENEMY IS HUNGRY, FEED HIM, AND IF HE IS THIRSTY, GIVE HIM A DRINK; FOR IN SO DOING YOU WILL HEAP BURNING COALS ON HIS HEAD." Do not be overcome by evil, but overcome evil with good. (Rom 12:14-21 NASB)

If we live by the Spirit, let us also walk by the Spirit. (Gal 5:25 NASB)

"For the Son of Man is going to come in the glory of His Father with His angels, and WILL THEN REPAY EVERY MAN ACCORDING TO HIS DEEDS. (Mat 16:27 NASB)
