"that the rough edges may be removed, the knots and uneven surface smoothed and fitted by the planing knife of God, you will be fitted by His grace for the heavenly building. But if you cling to self, and are not willing to endure the trying process of fitting for the heavenly building, you will have no place in that structure which will come together without the sound of ax or hammer. If your nature is not transformed, if you are not refined and elevated by the sanctifying truth for these last days, you will be found unworthy of a place among the pure and holy angels. 4T 258.1"
"For we are labourers together with God: ye are God’s husbandry, ye are God’s building."
Both passages use the metaphor of a building to describe spiritual growth and preparation for heaven.
