Persons who object to eternal security don't have any verses that say "lose salvation" or "lose faith." You don't even find those pairs of words in same verse. You find faith & fail once, but it is a negation. So you find persons who cannot trust the Lord Jesus with their eternal destiny pointing to this or that & trying to say that this implies or necessitates a loss of salvation. Of course Rom 1 has no such teaching.
I didn't find any verses that use the words "lose faith" or "lose salvation" but I did find these which seem to point to something similar.
1 Timothy 4:1 - The Spirit clearly says that in later times some will abandon the faith and follow deceiving spirits and things taught by demons.
Revelation 22:19 - And if anyone takes words away from this book of prophecy, God will take away from him his share in the tree of life and in the holy city, which are described in this book.
2 Peter 2:20-22 - If they have escaped the corruption of the world by knowing our Lord and Savior Jesus Christ and are again entangled in it and overcome, they are worse off at the end than they were at the beginning. It would have been better for them not to have known the way of righteousness, than to have known it and then to turn their backs on the sacred command that was passed on to them.
2 Peter 3:17 - Therefore, dear friends, since you already know this, be on your guard so that you may not be carried away by the error of lawless men and fall from your secure position.
Hebrews 6:4-6 - It is impossible for those who have once been enlightened, who have tasted the heavenly gift, who have shared in the Holy Spirit, who have tasted the goodness of the word of God and the powers of the coming age, if they fall away, to be brought back to repentance, because to their loss they are crucifying the Son of God all over again and subjecting him to public disgrace.
Hebrews 3:12-14 - See to it, brothers, that none of you has a sinful, unbelieving heart that turns away from the living God. But encourage one another daily, as long as it is called “Today,” so that none of you may be hardened by sin’s deceitfulness. We have come to share in Christ if we hold firmly till the end the confidence we had at first.
1 Timothy 1:18-20 - Timothy, my son, I give you this instruction in keeping with the prophecies once made about you, so that by following them you may fight the good fight, holding on to faith and a good conscience. Some have rejected these and so have shipwrecked their faith. Among them are Hymenaeus and Alexander, whom I have handed over to Satan to be taught not to blaspheme.
1 Corinthians 9:27 - No, I beat my body and make it my slave so that after I have preached to others, I myself will not be disqualified for the prize.
Romans 11:20-22 - But they were broken off because of unbelief, and you stand by faith. Do not be arrogant, but be afraid. For if God did not spare the natural branches, he will not spare you either. Consider therefore the kindness and sternness of God: sternness to those who fell, but kindness to you, provided that you continue in his kindness. Otherwise, you also will be cut off.
Luke 12:46 - The master of that servant will come on a day when he does not expect him and at an hour he is not aware of. He will cut him to pieces and assign him a place with the unbelievers.
Atwood, have fun trying to swat those flies.
