College students know that, in order to receive a diploma, they must complete their course of study. Giving up at the last hour throws away all that has been accomplished up to that moment. Without finishing the work, without reaching the end, there will be no reward.
For you need endurance in order to do God’s will and so receive what is promised.
Hebrews 10:36 NET
Salvation is conditional. The condition is faithfulness. Whoever perseveres to the end will be saved.
For the readers of this letter, the danger was abandoning the faith to return to Judaism, because of persecution.
For us, the greatest danger may well be the temptation of the world’s attractions, both in terms of immorality, as well as a sensual form of religion.
We all need perseverance, the attitude that refuses to quit, no matter the danger, the appearances or the difficulties.
