The requirements to host the Holy Spirit in our holy body

The Holy Spirit of God is holy. As such, the Holy Spirit of God cannot abide in a sinful body.
The believer of Jesus must first repent, confess their sins, stop sinning and pledge to keep all the laws of Jesus from now on, and get baptized to become a clean slate of a brand-new holy creature in Jesus to qualify to enter the holy circle of Heaven (1 Peter 1:15-16).

We must keep all the commandments of Jesus to host His Spirit

(15) If ye love me, ye will keep my commandments. (16) And I will pray the Father, and he shall give you another Comforter, that he may be with you for ever, (17) even the Spirit of truth: whom the world cannot receive; for it beholdeth him not, neither knoweth him: ye know him; for he abideth with you, and shall be in you. John 14:15-17 ASV

We must believe that Jesus is Jehovah God Almighty upon hosting the Holy Spirit in order to not die in our sins

Wherefore I make known unto you, that no man speaking in the Spirit of God saith, Jesus is anathema; and no man can say, Jesus is Lord [YHWH, YAHWEH, JEHOVAH], but in the Holy Spirit. 1 Corinthians 12:3 ASV
