If predestination pointed to being saved, then all would be predestined and all would be saved. And that is because (1) Christ died for all and (2) God desires the salvation of all. And since all are not saved, it means that predestination has another purpose....while clearly predestination points to being saved...
Reformed Theology began with the presumption that God has decreed the salvation of some and the damnation of others. Thus the Calvinistic doctrine of predestination or double predestination. But that was completely false, and Scripture refutes that completely.
Once we understand that God desires the ULTIMATE perfection of the saints, we can clearly see why he predestines those whom He justifies to also be glorified.
Which means that (1) salvation is entirely of the Lord and (2) God does nothing in half-measures. He wants all His children to be exact replicas of Christ, as Christ is an exact replica of the Father. But that will not happen until (1) "the flesh" (the sin nature) is eradicated and (2) the human body is rendered incorruptible, immortal, and glorious. And that is the purpose of the Resurrection/Rapture. A total transformation of the saints into the likeness of Christ.
