No, the verse you're referring to says the Lord is that Spirit. Since you insist on taking it out of context, you are quick to assume you know what it's saying. You don't.
2 Corinthians 3:17 Now the Lord is that Spirit: and where the Spirit of the Lord is, there is liberty.
Believe what is written. That scripture plainly says the Lord is the Spirit. There are other scriptures that say it too.
Jesus is the Spirit, glory.
1 Corinthians 15:45 So it is written: The first man Adam became a living being; the last Adam became a life-giving Spirit.
Did you read that? It says Jesus is a life-giving Spirit.
John 6:63
The Spirit gives life; the flesh counts for nothing. The words I have spoken to you--they are full of the Spirit and life.
How about that scripture?
Jesus says the Spirit gives life. He is that life-giving Spirit. He is the Spirit and spoke words that are full of the Spirit.
Isn't it wonderful? There is more.
God says that people will call Jesus God, Father, and the Holy Spirit, and that is what I call him.
Isaiah 9:6 HCSB For a child will be born for us, a son will be given to us, and the government will be on His shoulders. He will be named Wonderful Counselor, Mighty God, Eternal Father, Prince of Peace.
The scriptures say Jesus makes intercession for us.
Hebrews 7:25 Therefore he is able to save completely those who come to God through him, because he always lives to intercede for them.
The scriptures say the Spirit intercedes for us.
Romans 8:26
In the same way, the Spirit helps us in our weakness. We do not know what we ought to pray for, but the Spirit himself intercedes for us through wordless groans.
Romans 8:27
And he who searches our hearts knows the mind of the Spirit, because the Spirit intercedes for God’s people in accordance with the will of God.
Does that prove to you that Jesus is the Spirit?
Ephesians 2:18
For through him we both have access to the Father by one Spirit.
That scripture shows us that Jesus is that one Spirit in whom we have access to the Father.
2 Corinthians 3:17 Now the Lord is the Spirit, and where the Spirit of the Lord is, there is freedom.
2 Corinthians 3:18 And we, who with unveiled faces all reflect the glory of the Lord, are being transformed into His image with intensifying glory, which comes from the Lord, who is the Spirit.
Jesus is the Spirit. Revelation 2:7, 8, 11, 17, 29; 3:6, 13, 22; 14:13; 22:17 all tell us Jesus is the Spirit.
