To begin I'd appeal to Scripture like 1Cor1:9-10 which leads into the discussion against partiality in favor of different evangelists and teachers because Christ is not divided. And Eph4:1-6 which endeavors to instruct that we are all in the same body with one Spirit, one Lord, one God and Father of all. And then proceeding down through Eph4:7-16 speaking of the corporate maturity of the Body of Christ under the one Head - Jesus Christ - so we're (all) not tossed around by false teaching - because we're in unity of the Faith / the full experiential knowledge of Jesus Christ.
In one verse it probably looks like this expressed in 2 commands: NKJ 1John3:23 And this is His commandment: that we should believe on the name of His Son Jesus Christ and love one another, as He gave us commandment. IMO when reasoned out in the context of the entirety, this is Christianity from Alpha to Omega as it includes Love God and Neighbor in Christ which updates the 2 greatest commandments. At least part of omnilove as I think you call it. It also includes entering into Christ and growing to maturity in Christ which ties back to the unity in Christ mentioned above and what that unity is meant to produce.
Many ways to approach this but apart from much contemplation about your question, the above comes quickly.
Good approach. Applying it to this thread, let us examine the first few posts:
OP - Can a once truly saved believer backslide too much and lose the gift of salvation? If so do they need to repent and ask for forgiveness through Christ again? Thoughts are welcome and scripture too!
#2 - 20+ pages easy [humor is good]
#3 - I'm going to answer this in the simplest way I can think of. Yes, it IS possible to lose salvation... So correct me if I'm wrong,
but it seems to me like losing salvation IS possible, if you fall under any of these categories. And yes, repenting and asking for forgiveness is ALWAYS a good idea. [opinion/vote expressed with humility, which is good]
#4 - Consider also,
John 16:1. And it's nice to keep searching HIM out, there's lots of mercy and grace

We all need HIM [another vote for perseverance, expressed nicely]
#5 - Yes. If not, then much of scripture needs to be explained away, imo... It seems clear that there is a real danger is not maintaining faith to the end. The idea of “saving faith” is found nowhere in the Bible. There is faith that endures to the end and faith that fails. Faith that doesn’t endure does not result in salvation. [a third vote for perseverance, expressed humbly]
#6 - Quote of John 6:37. [indicates God's grace will persevere]
#7 - Can't help but notice you have not responded to any of the comments your Post has generated. Why not? Is it possible you were just "pfishing" with this Post? Are you familiar with the Lord's Prayer? Can you recite it? If so, then you already know the answer to the gist of your Post.
John 11:35) Jesus wept. Remaining Obedient Secures Eternity. [seems slightly argumentative, but a fourth vote for perseverane]
#8 - Best part - “So, correct me if I’m wrong…” [affirms that humility is good]
#9 - Still stuck on Salvation. I’m just amazed that no one on here can seem to move past this. Bro, are you born?
Are you still in your mom. Let’s discuss that. How do we really know that we’re born?! What if I become unborn?
Stop worrying about bs Move on! Your saved. Now start becoming useful. Who are you praying for/ ministering to?
Quit wallowing [Seems rather argumentative and bossy; unconstructive criticism]
#10 - If one claims that a person is saved by faith, then if one loses their faith then without faith then they couldn't be saved, correct?
And if they could be saved without faith, then obviously faith would not be required to be saved? [not sure what point is being made]
#11 - I cant find anything that says you can repent and be forgiven if you are willing. The closest thing to being beyond repentance is
Hebrews 6:4, and Is kinda awkward translation wise, the way I see it is you can't start all over again afresh per say, but you will suffer losses, and the more time you waste sinning the less you're going to be worth in the end. Understand that verse was written to get people to move beyond the basics and mature as Christians, a problem with witch I still suffer. [point is unclear because of omitting Heb.6:5-6]
#12 - I hope this is being ask because you don't know. They way its asked sometimes it (can) drives us apart not together. My thought always on this "lose" salvation is, explain how man is going to undo this "new man" this "new creation" that "new spirit" that only a GOD made new again. Now if salvation is nothing more then a simple choice.. ooh GOD HELP US ALL... Truth? I have no answer on how I would give it back or drop it or misplace it.. think even if every demon and fallen angel came at me.. if they could not even take it.. how can I lose it other then I really never had it.. just deceived my self never truly wanting to repent [a vote against apostasy based on false conversion]
#13 - Hey sis I was .. I don't know his name but he's a believer and talks about motor cycles and some new Honda bike thing. He was reading the manual (in the video) being funny that there were no pictures. I am awful with words sorry.... every time HE always shines.. so beautiful. Such a wonderful gift.. wow [seems off topic]
#14 - “Truly saved?” …you mean versus plain ol’ saved? “backslide too much?” …exactly what kind of backsliding?
selahsays going around sinning “too much“ might mean they haven’t been saved. Yikes! …better run [point seems unclear]
#15 - So, I'm saved. That means I can live as I wish and not worry if what I do is contrary to Gods Word. I do not have to worry about obeying God/Jesus, because I'm saved. Hey, that's good to know! [satirical?]
#16 - Did you mean "can't" repent? Because the Gospel of Jesus is all about repenting. Just saying. Regarding
Hebrews 6:4, maybe Gill's Exposition will help you This gave rise to, and seems to favour the error of Novatus, that those who fall into sin after baptism are to be cut off from the communion of the church, and never more to be restored unto it; contrary to the promises of God to returning backsliders, and contrary to facts, as well as to the directions of Christ, and his apostles, to receive and restore such persons; and such a notion tends to set aside the intercession of Christ for fallen believers, and to plunge them into despair Found here
Hebrews 6:4 - John Gill's Exposition of the Whole Bible - Bíblia Plus
You might also remember that Jesus Himself taught us to pray...
"forgive us our trespasses/debts as we forgive those who tresspass against us/our debtors... 6th Chapter of Matthew... what is funny is how the next two verses seem to be ignored by so very many...
14For if ye forgive men their trespasses, your heavenly Father will also forgive you:
15But if ye forgive not men their trespasses, neither will your Father forgive your trespasses.
Kinda shines a different light on what a lot of people teach, huh?
[seems to vote for perseverance]
#17 - Thank you, Blade! I find you
do have a way with words... words that have a way of exposing your heart and
expressing your love of God, and I for one appreciate it [nice aside]
#18 - Hello grateful; Here are words of Jesus that answers your questions;
Jhn 6:35 And Jesus said unto them, I am the bread of life: he that cometh to me shall never hunger; and he that believeth on me shall never thirst.
Jhn 6:36 But I said unto you, That ye also have seen me, and believe not.
Jhn 6:37 All that the Father giveth me shall come to me; and him that cometh to me I will in no wise cast out.
Jhn 6:38 For I came down from heaven, not to do mine own will, but the will of him that sent me.
Jhn 6:39 And this is the Father's will which hath sent me, that of all which he hath given me I should lose nothing, but should raise it up again at the last day.
Jhn 6:40 And this is the will of him that sent me, that every one which seeth the Son, and believeth on him, may have everlasting life: and I will raise him up at the last day. Peace [a vote against apostasy]
#19 - And here's the question of the day. What does it mean to believe on/have faith in Jesus? Is it believing he existed?
All we have to do is believe he died for our sins? Or is there more to our faith in him than believing the things he did?
[unanswered questions]
#20 - More way more. [vague answer]
All in all the posts on page one were civil with most folks believing apostasy is possible (but with minimal citing of Scripture),
and a few non-committal or unclear comments plus a couple of asides. (Not bad IMO :^)
