1.-Jesus Christ is the one who justifies us from sin before God.

      The Human beings must repent of our sins, believing in Jesus Christ as Savior. God justifies the one who is of the faith of Jesus. Romans 3: 23.

      The Bible says that Jesus Christ "was delivered for our transgressions, and resurrected for our justification." Romans 4:25.

2.-Jesus Christ does not need to be justified from sin.

      We know from Scripture that Jesus Christ is the Son of God (Luke 1:35). God himself participated in the activation of the ovum that gave birth to the body where he incarnated the Verb of God.

      We read in the Bible that Jesus Christ was holy in all his life, "who did not sin, nor was deceit found in his mouth" (1 Peter 2: 22). The demons themselves recognized that Jesus Christ is the Holy One of God (Luke 4:34).

3.-The justification of Jesus Christ in the Spirit.

      The Reina-Valera versions, with the exception of the RVA-2015, translate he justified in the Spirit. In the RVA-2015 version it says "justified by the Spirit" and the Bible of the Americas (LBLA) expresses vindicated in the Spirit. On the other hand, the BLPH version indicates that the Spirit gave testimony of him.

      The expression "justified in the Spirit" is not indicating that Jesus Christ had any connection with sin. We can understand this justification in two directions:

a.-The vindication of the privileges that he had before being incarnated.

      Jesus Christ voluntarily renounced his condition of glory to incarnate and die for sinners. Hours before his arrest he prayed to the Father of the following way: "Now, Father, glorify me next to you, with that glory that you have before the Verb was". John 17: 5; John 10: 17-18.

b.-Testimony that he really was the Son of God who had incarnated.

      The Holy Spirit was present at the time of the formation of the body of Jesus Christ. Also during his ministry (Luke 4: 18-19) and resurrection (Romans 1: 4).

      Jesus Christ was despised and rejected among men (Isaiah 53: 3), and was counted on sinners (Luke 23:32). Now he was recognizing that he was actually God manifested in flesh.

      The Bible says "that he was declared the Son of God with power, according to the Spirit of holiness, by the resurrection from the dead." Romans 1: 4.

Consider what I say, and the Lord give to you understanding in everything. 2 Ti. 2: 7.

And indisputably, great is the mystery of piety:
God was manifested in flesh,
Justified in the Spirit,
Seen from the angels,
Preached to the Gentiles,
Believed in the world,
Received up in glory. 1 Timothy 3:16.

23 For all have sinned, and come short of the glory of God,
24 being justified freely by his grace, through the redemption that is in Christ Jesus,
25 whom God has set as the propitiation through faith in his blood, to manifest his righteousness, because he has overlooked, in his patience, past sins,
26 with the aim of manifesting his justice at this time, so that he may be the just one, and the one who justifies the one who is of the faith of Jesus. Romans 3: 23-26.

35 And the angel answered and said unto him, The Holy Spirit shall come upon you, and the power of the Most High shall overshadow you; whereby also the Holy Being that will be born will be called Son of God. Luke 1:35.

22 who made no sin, nor was deceit found in his mouth; 1 Peter 2:22.

34 saying: Leave us; What do you have with us, Jesus of Nazareth? Have you come to destroy us? I know you who you are, the Holy One of God. Luke 4:34.

5 Now, Father, glorify me next to you, with that glory that I had with you before the world was. John 17: 5.

17 That is why the Father loves me, because I lay down my life, to take it again.
18 No one takes it from me, but I put it on myself. I have power to put it, and I have power to take it back. This commandment I received from my Father. John 10: 17-18.

18 The Spirit of the Lord is upon me,
Because he has anointed me to give good news to the poor;
He has sent me to heal the brokenhearted;
To proclaim freedom to the captives,
And sight to the blind;
To release the oppressed;
19 To preach the acceptable year of the Lord. Luke 4: 18-19.

3 about his Son, our Lord Jesus Christ, who was of the lineage of David according to the flesh,
4 who was declared Son of God with power, according to the Spirit of holiness, by the resurrection from the dead. Romans 1: 3-4.

who was delivered for our transgressions, and resurrected for our justification. Romans 4:25

3 Despised and rejected among men, a man of sorrows, experienced in brokenness; and as we hid his face from him, he was despised, and we esteemed him not. Isaiah 53: 3.

32 They also took with him two others, who were malefactors, to be killed. Luke 23:32.

Justified, then, by faith, we have peace with God through our Lord Jesus Christ; Romans 5: 1.
