BUT they did NOT have faith. The writer is not speaking of believers. Keep on reading.
For the earth which drinks in the rain that often comes upon it, and bears herbs useful for those by whom it is cultivated, receives blessing from God; but if it bears thorns and briers, it is rejected and near to being cursed, whose end is to be burned.
But, beloved, we are confident of better things concerning you, yes, things that accompany salvation, though we speak in this manner. For God is not unjust to forget your work and labor of love which you have shown toward His name, in that you have ministered to the saints, and do minister.
Even so, every good tree bears good fruit, but a bad tree bears bad fruit. A good tree cannot bear bad fruit, nor can a bad tree bear good fruit. Every tree that does not bear good fruit is cut down and thrown into the fire. Therefore by their fruits you will know them.
They went out from us, but they were not of us; for if they had been of us, they would have continued with us; but they went out that they might be made manifest, that none of them were of us.
Every good gift and every perfect gift is from above, and comes down from the Father of lights, with whom there is no variation or shadow of turning. Of His own will He brought us forth by the word of truth, that we might be a kind of firstfruits of His creatures.
You've kinda sorta mixed other passages in there with Heb 6 haven't you? The letter AND the warning against unbelief and falling away was to Hebrew Christians, period:
Take heed, brethren, lest haply there shall be in any one of you an evil heart of
unbelief, in
falling away from the living God: Heb 3:12
Believers produce fruit and endure because of God. Period.
This promotes the totally false premise that 'true Christians' can never make shipwreck of their faith. Why these admonitions then?:
......to present you holy and without blemish and unreproveable before him:
if so be that ye continue in the faith, grounded and stedfast, and not moved away from the hope of the gospel which ye heard, Col 1:22,23
Behold then the goodness and severity of God: toward them that fell, severity; but toward thee, God`s goodness,
if thou continue in his goodness: otherwise thou also shalt be cut off. Ro 11:22
Now I make known unto you brethren, the gospel which I preached unto you, which also ye received, wherein also ye stand, by which also ye are saved,
if ye hold fast the word which I preached unto you, except ye believed in vain. 1 Cor 15:1,2
but Christ as a son, over his house; whose house are we,
if we hold fast our boldness and the glorying of our hope firm unto the end...... for we are become partakers of Christ,
if we hold fast the beginning of our confidence firm unto the end: Heb 3:6,14
