When I get my new spiritual body I will, for now I fight along side the holy ghost my own wickedness.
Hebrews 12:4-14 guarantees how God corrects every child of God.
"But if you are without chastening, of which all have become partakers, then you are illegitimate and not sons." (Hebrews 12:8)
So, I would offer this goes for every child of God, not only ones with Jewish background. So, in case we are having problems with sin, and struggling, we need to actively seek God our Heavenly Father for how He is able to succeed in correcting us.
No hay nada problema demasiado grande por Dios.
Nevertheless, I dont feel people who think they need works plus faith will be cast out to hell. Most of them are fearful that they will be cast out of bad behaviour, but they already know without Jesus their works are meaningless.
But in case they are wrong, they can be having problems; and God is able to deeply correct us, so we don't spend our lives feeling as though we could fail and go to hell. Our Father's correction changes our character so we do better . . . in how His love has us living >
"Love has been perfected among us in this: that we may have boldness in the day of judgment; because as He is, so are we in this world." (1 John 4:17)
«En esto se ha perfeccionado el amor en nosotros, para que tengamos confianza en el día del juicio; pues como él es, así somos nosotros en este mundo.»
So, I would warn someone not to accept that they could fail for the rest of their lives or at the end of their lives. But, instead, trust how God is able to truly correct us. And this can not fail, if He does real correction in us so we become like Jesus.
God doesnt lose any believer.
I do believe this is a guarantee of salvation, but also we have the guarantee how God will correct us so we become like Jesus > Romans 8:29. So, I do not accept that Jesus saves a person, then does not finish what He has started.
"But he who is joined to the Lord is one spirit with Him." (1 Corinthians 6:17)
If we have given ourselves to Jesus, now each of us is
"joined" to Jesus in an almighty union. And God wins in this union!!! He changes our character so we become obedient and loving like Jesus. He does not leave us the way we were in sin with Satan. But we have been changed
"from the power of Satan to God" (in Acts 26:18).
So, I do not think it is wise to consider other possibilities will happen if we have trusted in Christ (Ephesians 1:12).
Because we could be helping someone to accept and excuse failure and not spend eternity with Jesus. God is able to succeed; our success depends on God; so we do not have to accept less than all He is able to do with us.
Nevertheless fellowship was never promise with faith only.
"faith working through love" (in Galatians 5:6)
And
"Love never fails," we have in 1 Corinthians 13:8.
So, I would not accept the possibility that a person who trusts in Jesus will then fail. In
"faith working through love," by the way, you will have fellowship with God . . . in His own love >
"Now hope does not disappoint, because the love of God has been poured out in our hearts by the Holy Spirit who was given to us." (Romans 5:5)
God's love
"in our hearts" changes our hearts to be like Jesus.
So, I do not think it is wise to accept any other possibility. But if a person is failing . . . pray with hope for the person, not being ready to accept failure, because God does not fail in us who have trusted in Jesus.
