One of the consistent themes of Hebrews is the danger of going back on your profession of faith in Christ. There are five distinct passages in Hebrews that warn us of the danger of going back. These are some of the most solemn words in Scripture. Therefore, one of the key words that Hebrews emphasizes is this word that we are looking at: endurance.
And we desire that each one of you show the same diligence to the full assurance of hope until the end, that you do not become sluggish, but imitate those who through faith and patience [endurance] inherit the promises. (Hebrews 6:11–12)
Faith and endurance. Some people will tell you that faith is all you need to claim God’s promise. But that is not true. You need faith and endurance. It takes both. As the author of Hebrews continued, “Therefore do not cast away your confidence, which has great reward. For you have need of endurance, so that after you have done the will of God, you may receive the promise” (Hebrews 10:35–36).
The word confidence means that you have freedom of speech. You can talk boldly about Jesus—about what He has done for you and what He will do for you. You have done the will of God, but you have not yet received the promise. What do you need? Endurance. You need to hold out from the point where you did God’s will and claimed the promise to the point where you actually receive the promise. Some people do the will of God and claim the promise, but they don’t hold out. Then, they say that it didn’t work. But it will not work without endurance. You need faith and endurance.
