Short answer, He is both. God was in Christ reconciling the world to himself.
Long answer, He is both.
In Luke Jesus quoted isa 61:1 and said he fulfilled it right then...
17 And He was handed the book of the prophet Isaiah. And when He had opened the book, He found the place where it was written:
18 “The Spirit of the LORD is upon Me,
Because He has anointed Me
To preach the gospel to the poor;
He has sent Me [i]to heal the brokenhearted,
To proclaim liberty to the captives
And recovery of sight to the blind,
To set at liberty those who are [j]oppressed;
19 To proclaim the acceptable year of the Lord.”
20 Then He closed the book, and gave it back to the attendant and sat down. And the eyes of all who were in the synagogue were fixed on Him. 21 And He began to say to them, “Today this Scripture is fulfilled in your hearing.”
If you read the same passage from Isaiah down to verse 8. The speaker (obviously Jesus) says ... “For I the LORD love Justice...”
Now ask yourself, when, where, did the speaker change?
Isaiah 61:1-8
The Spirit of the LORD God is upon Me,
Because the Lord has anointed Me
To preach good tidings to the poor;
He has sent Me to [a]heal the brokenhearted,
To proclaim liberty to the captives,
And the opening of the prison to those who are bound;
2 To proclaim the acceptable year of the Lord,
And the day of vengeance of our God;
To comfort all who mourn,
3 To [b]console those who mourn in Zion,
To give them beauty for ashes,
The oil of joy for mourning,
The garment of praise for the spirit of heaviness;
That they may be called trees of righteousness,
The planting of the Lord, that He may be glorified.”
4 And they shall rebuild the old ruins,
They shall raise up the former desolations,
And they shall repair the ruined cities,
The desolations of many generations.
5 Strangers shall stand and feed your flocks,
And the sons of the foreigner
Shall be your plowmen and your vinedressers.
6 But you shall be named the priests of the Lord,
They shall call you the servants of our God.
You shall eat the riches of the Gentiles,
And in their glory you shall boast.
7 Instead of your shame you shall have double honor,
And instead of confusion they shall rejoice in their portion.
Therefore in their land they shall possess double;
Everlasting joy shall be theirs.
8 “For I, the LORD love justice;...”
Notice in verse 1 Jesus speaking, “the spirit of the LORD is upon (me).
And in verse 8 “I the LORD”
When did the speaker change?
