In the Holy Spirit as a Divine Person as God the Father and God the Son. The Spirit is the sanctifying power which enables a believer to live a holy life.
"When the Counselor comes, whom I will send to you from the Father, the Spirit of truth who goes out from the Father, he will testify about me."
Do not get drunk on wine, which leads to debauchery. Instead, be filled with the Spirit.
Make every effort to live in peace with all men and to be holy; without holiness no one will see the Lord.
I Peter 1:15-16
But just as he who called you is holy, so be holy in all you do; for it is written: "Be holy, because I am holy."
