Amen!!! We have a responsibility in our sanctification, why? "for it is God who works in you, both to will and to work for his good pleasure." It's our sanctification, this part our salvation, it's not our salvation, we will be fully sanctified as well as fully saved the we receive our blessed our our glorified bodies. We are in the process of sanctification here on earth, this is what we are responsible for in working with God in fear and trembling, it's that part of salvation that we are work out, not working for, big difference.
When you are married and are having problems you work them out, you can work for it because you are already married, the same applies here, we are already saved, so we can not work for, but we can work it out. What do you think we are called the bride or children, these are unbreakable bonds, yes you can get a divorce, but you are still one with her/him because let not man put asunder what God has put together, you may be legally divorced, but spiritually you are still married. Children are your children forever, they may do something that you disapprove of but, that does not end the relationship of shared DNA, that's forever as well. Once you've been united to Christ there is nothing that can separate you from the love of god that is in Christ Jesus our Lord. Here's a list of thing that can not separate you from that love.
Romans 8:37-39 "No, in all these things we are more than conquerors through him who loved us.38 For I am sure that neither death nor life, nor angels nor rulers, nor things present nor things to come, nor powers,39 nor height nor depth, nor anything else in all creation, will be able to separate us from the love of God in Christ Jesus our Lord."
I've showed that to people and they will yes nothing can separate us, but we can give it up or forfeit it and I point them to "nor anything else in all creation". Then I ask them are you not anything else in all creation? When it say nothing, it means nothing and God knew people would still try to exalt themselves about all things, so he put, "anything else in all creation". All of it is all based on a man exalted salvation, weather losing it, your faith saves you, your faith keeps you saved, I repent then God gives me grace or whatever else exalts man over God.
We have full responsibility in our sanctification process, we have full reliability for our salvation on Christ because of His imputed righteousness. Because as I mentioned, the standard is to be perfect as our heavenly Father is perfect and we all fail every second of our lives, so no one could be saved, but for the grace of God in Christ. Any type of salvation by any type of self maintenance are works of the Law, no longer of grace be done. I mean lest call it what it is, sin, falling short of the glory of God and we can never attain to His glory, so we always fall short of salvation, unless it is all by His grace, because of to depends on us, we forever fall short. Being saved is not God making us better, now we can reach the glory of God and if we keep it we are saved, if we do not we lose it, no, we are always short of His glory or Hid perfection and can never reach it. Anything else is a god of your own understanding and not the God of creation.
