Those who persevere sall be saved. Also saved are those who have a simple faith in Him.. The Greek work PISTIS is translated as faith in some passages, trustworthy in others, also as Bible doctrine in our thinking processes elsewhere.
Demons might comprehend some facets of our Lord and Savior's status, but in their mind, they are not thinking with the mind of Christ. They are not exhibiting a faith in Him the same as Christ had faith in the Father (Rom 3:22-26).
We are saved from condemnation, which we born into from the first Adam, by faith alone in the second Adam, not by any works. Our salvation is purely the work of God. This is the good news. Specifically, God the Holy Spirit in the regeneration of our spirit, where God creates a human spirit life in us.
Once we have that spirit life, we have eternal life.
Rom 8:38 For I am persuaded, that neither death, nor life, nor angels, nor principalities, nor powers, nor things present, nor things to come, Rom 8:39 Nor height, nor depth, nor any other creature, shall be able to separate us from the love of God, which is in Christ Jesus our Lord.
Even after salvation from condemnation to the Lake of Fire, we still have volition. In our volition, our will, we might intend something separate from God, i.e. the very definition of sin.
When we sin, we are not in fellowship with God. That is a completely different issue than having a human spirit and eternal life. When we sin , we do NOT lose our spirit life. Our living after salvation is an entirely different process than when we were originally saved. (Other than both are the works of God through our faith in Christ.) In the regeneration of our spirit, God creates our rebirth, a new spirit life, something not possessed by unbelievers. Sin no longer separates us from that new spirit because God the Son in His humanity, sacrificed His spirit on the Cross. Additionally, Christ only made one sacrifice, not many for multiple occasions of sinning and dieing. Instead, the issue of spiritual death has been settled once and for all on the Cross.
After salvation, we now have a new hope established for us, again through faith in Christ.
After salvation, our challenge is to remain in fellowship with Him first, study the Word from our Pastor-teacher, allowing God the Holy SPirit to bring that Word and make it supernaturally perceived in our spirit.
While remaining in fellowship with Him, God the Holy SPirit makes that LOGOS understood in our mind as an intellectual knowledge or GNOSIS. While remaining in fellowship with Him, God the Holy Spirit then takes that GNOSIS in our mind, the mental part of the soul and transfers to into an ouward knowledge or EPIGNOSIS in our heart, or the outbreathing portion of our soul. Again, while we remain in fellowship with Him, He is able to take the portions of knowledge in our mind and place them in categories for our future rememberance, recall, and application from our hearts.
Our minds and hearts are still scarred from previous wrong-thinking when we sinned in the past. We continually renew our thinking daily, with the 'mind' of Christ, thereby allowing the Holy Spirit to continue to sanctify us, cleanse our thinking, our mind, our hearts, so that we then have the tools available to us to apply when we become doers of the Word.
You are correct to say, "following Him means believing and living that belief through their thoughts, words, and deeds"
After salvation, He continues to sanctify us by our residing in His system of power through the Holy Spirit. It begins be our hearing the LOGOS, remaining in fellowship with Him, thinking that LOGOS in our mind, remaining in fellowship with Him, remaining in faith-rest with Him, allowing God the Holy Spirit to do all the work in our mind and transferring that GNOSIS in our mind to EPIGNOSIS in our heart, agin by our remaining in fellowship with Him. How do we remain in fellowship with Him? By taking on the mind of Christ and thinking theough faith in Him in ALL things.
ALL faith comes from God, including our continueing in faith and new doctrine being filed categorically in our hearts for our use in problem solving throughout life.
In this fashion we are able to always think, walk, and work through faith in Him. There is no need for any alternate morality.
We are in a sense hamsters on the hamster wheel, but the wheel isn't a wheel of life, it is a wheel of fellowship. Unbelievers never get on that wheel because this wheel is outside the cage of condemnation and Christ is the small gate to escape to eternal life. As that wheel turns, God does all the work n us, further sanctifying us or setting us apart to perform good works from His perspective in accordance with His plan.
How about that we agree about something. :-)
Thankfully the gift of GRACE also comes with a counselor who will guide me in my Christian walk.
