god selects those who are useful to him in that manner to be his while on earth. he uses everyone else, just in different ways. we respond to his call because we cannot deny it. none can break from the compelling nature of him. you don't respond because of something good about you, you respond because he tells you to. thus you are saved by grace. through the faith that he enables in you. works develop as a result of the inherent changes that happen in the truly bought but are otherwise useless and meaningless outside of evidence. however, so many who claim to be 'saved' are lacking in so many ways that i question their fire insurance.
