I believe when a believer has reached a "certain point", in one's "Temple built without hands", or as Peter said: "A Spiritual house", (towards) "A Holy Priesthood", in (for) "Spiritual sacrifices acceptable to God By Jesus Christ?" That, in the "moving beyond the principle doctrines of Christ, towards Spiritual maturity?"
It should behoove a believer, in a "spiritual sense" to do some of the offerings, such as "offerings of first fruits" (such as fruit of the Holy Spirit, as it develops...love, joy, kindness, peace, long suffering, temperance, etc) unto Our Father. As well as offerings such as "wave offerings and heave offerings", etc.)
This should happen when one picks up one's own cross from Jesus, and goes unto our Father in Heaven. As Jesus confesses one before our Father, as we confess Christ before men.
It is in this fashion, I believe, that eventually? Not only will one have the "Spirit of Christ" within one's own Temple, built without hands. But also, one's Spiritual House (Temple), will be "sanctified" enough, where the "Spirit of God" will "take up residence" within one's House (Temple).
These "efforts" or "works", are not only profitable in a "cementing" (if you will) of one's salvation. But, also meet (profitable) in keeping one's election assured. Inasmuch as "sanctification" grows. Not to mention one's Spiritual roots!
But? That's just me.
