Rewards are a different thing. Believers will be rewarded according to their faithful stewardship.
There are five crowns mentioned in the New Testament that may be earned by a believer:
1. THE INCORRUPTIBLE CROWN (I Cor. 9:25: given for faithfully running the race for Jesus and being temperate in all things.
2. THE CROWN OF REJOICING (I Thess. 2:19): given to faithful soul-winners.
3. THE CROWN OF RIGHTEOUSNESS (II Timothy 4:8): given to all who are in love with the second appearing of Jesus.
4. THE CROWN OF LIFE (Revelation 2:10): given to martyrs for His name.
5. THE CROWN OF GLORY (I Peter 5:4): given to faithful pastors.
1 Cor. 9:24 --> Do you not know that in a race all the runners run, but only one gets the prize? Run in such a way as to get the prize.
Ill just take salvation. You can wear your hat around. It makes no difference to me.
