God is "bringing many sons unto glory." This is the great work which he undertook before the world began, the work to which he has attached the honor of his name, the work which he will accomplish (Rom. -30). Everything God does, has done, or shall hereafter do, everything God permits, has permitted, or shall hereafter permit, is subservient to this great work. He is "bringing many sons unto glory!"
Notice the Apostle's use of that word "glory." He uses it interchangeably with the word "heaven". He makes the two terms synonymous. He calls heaven "glory" because...
HEAVEN IS A GLORIOUS PLACE. We preach about it, sing about it, and write about it, but we really know very little about heaven. "As it is written, Eye hath not seen, nor ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love him" (I Cor. 2:9). We will never know the glory of glory until we are in glory.
HEAVEN IS A PLACE INHABITED BY GLORIOUS PERSONS (Heb.12:22-24).God is there,Father,Son and Holy Spirit. Christ, the Lamb, in whom God is revealed and known, is there. All the holy angels are there. All God's elect will be there justified and made perfect in Christ!
