I do not see a believer being condemned to the eternal lake of fire forever and ever in these verses.I believe that no one will be able to snatch me out of His hand.
That is called faith. I believe this.
There are many many exceedingly precious promises, just as you have listed, and I believe them and have faith in what he promised me.
as Peter both taught us, and stirred us up to remember -
1 Simon Peter, a bondservant and apostle of Jesus Christ, To those who have obtained like precious faith with us by the righteousness of our God and Savior Jesus Christ: 2 Grace and peace be multiplied to you in the knowledge of God and of Jesus our Lord, 3 as His divine power has given to us all things that pertain to life and godliness, through the knowledge of Him who called us by glory and virtue, 4 by which have been given to us exceedingly great and precious promises, that through these you may be partakers of the divine nature, having escaped the corruption that is in the world through lust. 5 But also for this very reason, giving all diligence, add to your faith virtue, to virtue knowledge, 6 to knowledge self-control, to self-control perseverance, to perseverance godliness, 7 to godliness brotherly kindness, and to brotherly kindness love. 8 For if these things are yours and abound, you will be neither barren nor unfruitful in the knowledge of our Lord Jesus Christ. 9 For he who lacks these things is shortsighted, even to blindness, and has forgotten that he was cleansed from his old sins. 10 Therefore, brethren, be even more diligent to make your call and election sure, for if you do these things you will never stumble; 11 for so an entrance will be supplied to you abundantly into the everlasting kingdom of our Lord and Savior Jesus Christ. 12 For this reason I will not be negligent to remind you always of these things, though you know and are established in the present truth. 2 Peter 1:1-12

I see what a believer will experientially live and think like if a believer does not live the Christian life.
9 For he who lacks these things is shortsighted, even to blindness, and has forgotten that he was cleansed from his old sins.
It says that they have "forgotten" that they were cleansed. It doesn't say that they are no longer cleansed.
