Without holiness no man shall see the Lord. Hebrews 12:14
To possess this holiness is a necessary and indispensable meetness for the inheritance of the saints in light; but this meetness must be wrought in us by the power of God's grace, for I am sure that in ourselves of it we have none. But see its necessity. What happiness could there be in the courts of bliss unless we had a nature to enjoy it? Unless we were made capable of seeing Christ as he is, and enjoying his presence for evermore, heaven would be no heaven to us. Nothing unclean or unholy can enter there. Sanctification therefore must be wrought in us by the power of God, to make us meet for the heavenly inheritance, and he therefore communicates of his Spirit and grace to give us heavenly affections, holy desires, gracious thoughts, tender feelings; and above all that love whereby he is loved as the altogether lovely. By the sanctifying operations of his Spirit, he separates us from everything evil, plants his fear deep in the heart, that it may be a fountain of life to depart from the snares of death; and works in us a conformity to his suffering image here that we may be conformed to his glorified image hereafter. Thus there is a perfect and an imperfect sanctification--perfect by imputation, imperfect in its present operations. But the one is the pledge of the other; so that as surely as Christ now represents his people in heaven as their holy Head, so will he eventually bring them to be forever with him in those abodes of perfect holiness and perfect happiness which are prepared for them as mansions of eternal light and love.
