No. Jesus was not God in an earth-suit, He was fully God AND fully man. And He did not take on sinful humanity, He was the first and only human being born sinless. Dude, you are all over the map in your beliefs, which is reflected in this thread which is all over the map as well.
Just to add to the last post:
1 John 5:7 For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one.
John 1:1 In the beginning was the Word, and the Word was with God, and the Word was God.
John 1:14 And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth.
John 1:14 tells us the Word was made flesh, dwelt among us, and the Word had the glory as of the
only begotten of the Father. So we can conclude that the Word can only be the Lord Jesus Christ. John 1:1 tells us that the from the beginning was the Word and the Word was God. Yes the Lord Jesus Christ is the creator of Heaven and earth!
2 Corinthians 5:21 For he hath made him to be sin for us, who knew no sin; that we might be made the righteousness of God in him.
Hebrews 9:12 Neither by the blood of goats and calves, but by his own blood he entered in once into the holy place, having obtained eternal redemption for us.
The Lord Jesus Christ was not a part of sinful humanity. He was literately turned to sin and put to death on the cross for us. The Lord was the ultimate sacrifice fulfilling the Law!
Matthew 5:17 Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfill.
For the original question, The Lord can justify the ungodly and still maintain His integrity to the law because he fulfilled the law by his Blood which was the perfect sacrifice. All of the animal sacrifices in the Old Testament on the day of Atonement were just sin coverings for 1 year then had to be repeated the following year. The Lord obtained ETERNAL REDEMPTION for us by belief and faith in what he has done for me and you!
Please remember if you have a question about the Bible to pray for guidance and understanding, and search the scripture because it is a continuing revelation. Also please remember you must not mix Mosaic Law with Grace! The two cannot go together Law can only convict you of sin and cannot save you. You can only be saved by the Grace of the Lord Jesus Christ and by having faith in
THE GOSPEL which can be found in 1 Corinthians 15:1-4
