Yahweh original plan is to dwell in man and He can only do so as a spirit. And all believers are the temple of the Holy Spirit, that was why Yeshua told his disciples it is to your advantage that I go so I can come back again into you as Holy Spirits and dwell inside you.
Holy Spirit is God and He is the power of God and He is all we need to be god but He cannot dwell inside a sinners and without Holy Spirits we cannot not live a holy life. Get the Holy Spirit and power to continue will come.
