You seem to think that a single moment of repentance is all that God requires instead of a lifetime of righteousness.
Stop looking at whether you can save yourself with your works.
Look at how you can damn yourself with your works.
1 Corinthians 6:9-10
9 Know ye not that the unrighteous shall not inherit the kingdom of God? Be not deceived: neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor abusers of themselves with mankind,
10 Nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners, shall inherit the kingdom of God. |
Obeying laws as a means to righteousness is the proper way for children in Christ to begin to learn about righteousness, since the law is our schoolmaster and many Christians have never learned what the schoolmaster teaches.
Galatians 3:24
24 Wherefore the law was our schoolmaster to bring us unto Christ, that we might be justified by faith. |
Obeying the law is not an end, since you are expected to learn the principles and then apply them to your life when you leave the schoolmaster
If you are rebelling against the teachings of the schoolmaster, then you are stuck in unrighteousness.
If you have a heart that is rebelling against the law that God gave, then you have a disobedient heart to whatever God said, just like the children of Israel you are referring to.
People are called when they hear the Word.
Some will reject it and others will believe.
Those that believe will either repent and obey, or rebel against obeying.
Those that repent and obey are the ones that Jesus chooses to be written in the Book of Life, are given the Holy Spirit as a pledge that they will be saved in the coming salvation.
Those that repent and obey will either continue in their faith or fall from it.
Those that continue in their faith will not be blotted from the Book of Life.
Those that quench the Spirit and fall from the faith will have their names blotted out from the Book of Life if they remain in continuous rebellion.
Those that are still written in the Book of Life at the end of their life will receive salvation in the Resurrection of the Righteous.
Salvation is the end of faith, not the beginning.
1 Peter 1:9
9 Receiving the end of your faith, even the salvation of your souls. |
