HE BECAME SIN THAT WE MIGHT BECOME RIGHTEOUS

"Behold, his soul which is lifted up is not upright in him: but the just shall live by his faith" (Hab. 2:4).

"For therein is the righteousness of God revealed from faith to faith: as it is written, The just shall live by faith" (Rom. 1:17).

"But that no man is justified by the Law in the sight of God, it is evident: for, The just shall live by faith" (Gal. 3:11).

"And be found in Him, not having mine own righteousness, which is of the Law, but that which is through the faith of Christ, the righteousness which is of God by faith" (Phil. 3:9).

"Now the just shall live by faith: but if any man draw back, my soul shall have no pleasure in him.  But we are not of them who draw back unto perdition; but of them that believe to the saving of the soul" (Heb. 10:38-39).

"But without faith it is impossible to please Him: for he that cometh to God must believe that He is, and that He is a rewarder of them that diligently seek Him.  By faith Noah, being warned of God of things not seen as yet, moved with fear, prepared an ark to the saving of his house; by the which he condemned the world, and became heir of the righteousness which is by faith" (Heb. 11:6-7).

"For what saith the Scripture? Abraham believed God, and it was counted unto him for righteousness. Now to him that worketh is the reward not reckoned of grace, but of debt. But to him that worketh not, but believeth on Him that justifieth the ungodly, his faith is counted for righteousness" (Rom. 4:3-5).

"Even as Abraham believed God, and it was accounted to him for righteousness. Know ye therefore that they which are of faith, the same are the children of Abraham. And the Scripture, foreseeing that God would justify the heathen through faith, preached before the Gospel unto Abraham, saying, In thee shall all nations be blessed. So then they which be of faith are blessed with faithful Abraham" (Gal. 3:6-9).

"And the Scripture was fulfilled which saith, Abraham believed God, and it was imputed unto him for righteousness: and he was called the Friend of God" (Jam. 2:23).

The Father made the sinless Jesus to be sin for us, 

so that we might be made the righteousness of God by faith in Him!
