Moreover whom he did predestinate, them he also called: and whom he called, them he also justified: and whom he justified, them he also glorified. Romans 8:30
Predestinate, called, justified, and glorified! So many wonderful doctrines in one sentence! And in the past tense too. Of course, the book of Romans is like that, giving the credit to God, totally apart from any effort on our part.
I would say, that among those who read these promises, the first three are well known, along with scriptures from other parts of the Bible that also proclaim them. But how many of us consider glorification other than applying to God?
A friend of mine told me "I've been whittled down to a little stump." All I could say to him is that that is where God wants us, humbled down to where He can talk to us. It has been my experience that, with Jesus as our example, humility is one of the most understood ideas in scripture.
Predestination, calling, and justification are also known, though the first is sometimes not believed in. But how many of us have heard sermons on, or studied, our glorification? I know I have not.
To many, myself included, the thought of being glorified is alien to our minds. Being denigrated, lowered, and even despised, is closer to our experience. These we may share with Jesus, and identify with him through our experience. Perhaps it is the futurity of this wonderful promise that keeps us from thinking about it, though we should do so.
Maybe we need a "glorification break" where we think of ourselves and those we love, finally being glorified with and through Christ? We do not deserve it on our own, but He does, and He will share his glory with us.
