Or, more biblically, faith alone does save (justify before God) Eph. 2:8-9. Faith being grown by works saves (sanctifies, justifies before men) James 2:14-26. Faith alone glorifies (Rom 8:30).
Fruit indicates that your faith is growing. People who have faith and not a lot of fruit are pruned by God, John 15, those who fail to abide in Christ are cast down, (physically punished). They are still eternally saved, but they are failing to obey. Failing to follow the great High priest,
Heb 5:8Son though he was, he learned obedience from what he suffered
9and, once made perfect, he became the source of eternal salvation for all who obey him
10and was designated by God to be high priest in the order of Melchizedek.
The source of eternal salvation is continual salvation, sanctification. It has to be thus, did the high priests of the OT save the people again and again in an initial way? Did the people every year lose their salvation and have to be saved again? No! He saved/sanctified them in a continual way. Same with this passage from Hebrews.
Hebrews is about continuing salvation, as is clear from the beginning of the book, about entering rest, Heb 4:1 Therefore, since the promise of entering his rest still stands, let us be careful that none of you be found to have fallen short of it.
Hebrews is the doctoral dissertation of the NT, failure to understand it has led many to have weird views. Read it simply, and understand how it asserts the supremacy of Christ in every way, as the author and finisher of our faith. How do we finish our faith? It takes effort on our part, and if we fall away, we are in danger of the chastening fire of God, but we are not in danger of losing that which God has laid hold of us for, initial and positional salvation. We are only in danger of losing sanctification, continual deliverance from the power of sin in our lives.
May God's words truly be understood.
