God the Father has one offer to those who believe and that is eternal life. God the Son otoh is Him to Whom the rewards are His to give. Christ is that aspect of Hebrews that speaks of the belief in God as One Who rewards and to which belief is essential. The rewards are given on the day of the Lord and only those believers who have overcome the world, satan and self will be recipients qualified to participate in His pre-eternal reign. And of those qualified not all will be safe from having to face the opportunity to side against God again. Of those many that are called, few are indeed the chosen. They will be the ones wearing their crowns for eternity. At this point I imagine it like looking at the coat of many colours the Mighty Father has made for His favoured children, all the colours of the many rewards available.Those not favoured in this way will be raised for eternity as their reward for belief but will wear God’s displeasure for eternity. Rewards have been given as the incentive, the prize for endurance. Yet only those things that have been wrought thru Him will in fact endure to the end.
