Scripture emphasizes there is just one Spirit. Paul, for example, wrote, “There is one body and one Spirit.”[1] Yet Scripture also speaks of the Spirit of God (the Father), the Spirit of Christ, and the Holy Spirit. Moreover, each Spirit is said to be in believers.
1 Corinthians 3:16 (NASB) Do you not know that you are a temple of God and that the Spirit of God dwells in you?
1 Corinthians 6:19 (NASB) Or do you not know that your body is a temple of the Holy Spirit who is in you, whom you have from God, and that you are not your own?
Galatians 4:6 (NASB) Because you are sons, God has sent forth the Spirit of His Son into our hearts, crying, “Abba! Father!”
How is this possible if there is only one Spirit? The answer is found when we understand just who or, more accurately, what the Spirit is. https://onegodworship.com/the-spirit-of-christ-and-the-spirit-of-god/
