Is our faith given by God or can we grow it?

Question from moody radio listener: Romans 12:3 says we are distributed a certain amount of faith but Romans 10:17 says faith comes from hearing the word of God. If we are distributed our faith, then it cannot grow but can our faith grow? Answer from the two Michaels from open line moody radio: Romans 12:3 the phrase measure of faith is really debated. I think the best understanding of that phrase in Romans 12:3 is not so much that we are given an amount of faith though that is frequently understood that way. The idea is the word measure can actually mean an instrument that we can measure ourselves against and what we can measure ourselves against is faith, that is saving faith. We are all saved by grace through faith, then we are going to think accurately and humbly about ourselves. So if we see ourselves against the standard of saving faith, then I am no better than Rydelnik and Rydelnik is no better than me and we are no better than you are because we are saved by faith. Having said that, that's about saving faith but in Romans 14, we have another aspect of faith - our strongly held spiritual beliefs or opinions. In Romans 14:1, it says as to one who is weak in faith, welcome him but not to quarrel over his opinion. One person has faith that he may eat anything while the weak person eats only vegetable. So we have here people who are strong in their spiritual beliefs and others who are weaker and even others who are weak can grow strong as they become informed about what scripture says about the host of different issues. Their strength can grow and develop but that's a different aspect of faith than saving faith. I think God imparts to us the ability to have saving faith. I am not sure that that grows but our ongoing relationship with God based on our knowledge of the truth of the word, that can grow and that can deepen and become much stronger. Romans 12 3 For I say, through the grace given unto me, to every man that is among you, not to think of himself more highly than he ought to think; but to think soberly, according as God hath dealt to every man the measure of faith.  -kjv Romans 10 17 So then faith cometh by hearing, and hearing by the word of God.  -kjv Romans 14 1Him that is weak in the faith receive ye, but not to doubtful disputations. -kjv Above explanation given on moody radio openline on December 12, 2015.
