That sounds like the Mormon gospel from the book of Mormon. 2 Nephi 25:23 - For we labor diligently to write, to persuade our children, and also our brethren, to believe in Christ, and to be reconciled to God; for we know that it is by grace that we are saved, after all we can do. In other words, do all you can or else the Lord will not be able to save you. Yet God's word says, "saved by grace through faith, not of ourselves, not of works, lest anyone should boast." (Ephesians 2:8,9) So, is it after all YOU can do or after all that Christ has DONE?
You're simply mischaracterizing assertions that God must be obeyed to be saved in order to conform them to your work-phobic PCTSD (Post Catholic Traumatic Stress Disorder).
Doing everything we can to be saved is just basic common sense. Any child would want to please his father.
But you turn that around to mean doing everything we can to earn salvation. No it's not that at all. It's doing everything we can to guard the salvation we haven't earned so that we are not led astray and fall from the faith
