When he has been approved,
he will receive the crown of life.
Eternal life is the crown that God has promised to those who love Him. It is the believer’s ultimate reward. Although we presently experience some of the benefits of eternal life, we possess it on promise; some day we will receive it in its fullness. We are still waiting to enter into our future reward. At the Lord’s coming, He will grant to us the fullness of eternal life.
The apostle Paul expressed a similar thought: “Finally, there is laid up for me the crown of righteousness, which the Lord, the righteous Judge, will give to me on that Day, and not to me only but also to all who have loved His appearing” (2 Tim. 4:8). When Christ returns for the church, Christians will be granted a life of eternal righteousness. We will all receive the same crown consisting of the rewards of eternal life, righteousness, and glory.
Endurance does not earn eternal life. However, endurance is the proof of true faith and love, and that is rewarded by the fullness of eternal life.
