Once that choice is made - they are justified, their sins are forgiven, they are enabled to do as Paul said in Romans 8 "BY the SPIRIT put to death the deeds of the flesh". That is a work that can only be engaged in by the saved. But that would include submitting to the teaching of Christ even in Matt 18 rather than being at war against Christ's Word.-
Eph 2:8 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:
Eph 2:9
Not of works, lest any man should boast.
Tit 3:5
Not by works of righteousness which we have done, but according to his mercy he saved us, by the washing of regeneration, and renewing of the Holy Ghost;
requirement [rɪˈkwaɪəmənt]
n
1. something demanded or imposed as an obligation Latin is no longer a requirement for entry to university
2. a thing desired or needed
3. the act or an instance of requiring
You have made works a requirement for salvation, just because you place works as an after requirement rather than a prerequisite does not mean that you are not teaching works salvation which is what Eph 8-9 says.
Ironically you are doing exactly what this verse teaches
Gal 5:4 Christ is become of no effect unto you, whosoever of you are justified by the law; ye are fallen from grace.
This verse is talking about those who would seek their justification from the law(works based), Ryan you have fallen from Grace, you are no longer seeking justification by grace through faith because you have added unto Faith.
Rom_11:6 And if by grace, then is it no more of works: otherwise grace is no more grace. But if it be of works, then is it no more grace: otherwise work is no more work.
The moment you add any sort of requirement or work to grace, grace ceases to be grace, for you to teach that salvation requires any effort on our part other than believing and trusting Christ (faith) is to add works to grace, therefore you have fallen from grace as is said in Gal 5:4, Gal 5:4 has nothing to do with losing your salvation.
