(Rom 8:17) “And if children, then heirs; heirs of God, and joint-heirs with Christ; if so be that we suffer with him, that we may be also glorified together.” The last part is referring to the miracle of God in the salvation experience. I am on the cross with Jesus, the accusation of my sins being nailed to it (Col 2:14). In the same experience I am buried with Him. And then, I am glorified sitting in the heavenlies already in the mind of God (Eph 2:6). So, in reality it is saying, “IF you have been saved.”
