The prize Paul is writing about is Salvation that has not yet been grasped in its fullness. For as Believers, we have yet to fully experience all the benefits of redemption. Yet the saving process and Jesus’ resurrection have already begun in our life as Christ Jesus “took hold” of us. We need to always remember though that our justification is by faith alone and on the basis of Christ’s merits and not on anything we’ve done. So, we push ahead, confident in the already and looking forward to the not yet.
