Rom 1:17 For in it God's righteousness is revealed from faith to faith, just as it is written: The righteous will live by faith.

Only will the righteous will live by faith. The bible says to be "full of faith" as Stephen was, to the point of death, to be as Abraham father of faith and that you can be weak or strong in your faith.

I believe the only way someone can be weak in there faith is by not reading there bible, there instruction manual, and to strengthen there faith by reading the bible.


Matthew Henry said "The just shall live by faith. Just by faith, there is faith justifying us; live by faith, there is faith maintaining us; and so there is a righteousness from faith to faith. Faith is all in all, both in the beginning and progress of a Christian life. It is not from faith to works, as if faith put us into a justified state, and then works preserved and maintained us in it, but it is all along from faith to faith, as 2Co_3:18, from glory to glory; it is increasing, continuing, persevering faith, faith pressing forward, and getting ground of unbelief. To show that this is no novel upstart doctrine, he quotes for it that famous scripture in the Old Testament, so often mentioned in the New (Hab_2:4): The just shall live by faith. Being justified by faith he shall live by it both the life of grace and of glory. The prophet there had placed himself upon the watch-tower, expecting some extraordinary discoveries (Rom_1:1), and the discovery was of the certainty of the appearance of the promised Messiah in the fulness of time, not withstanding seeming delays. This is there called the vision, by way of eminence, as elsewhere the promise; and while that time is coming, as well as when it has come, the just shall live by faith. Thus is the evangelical righteousness from faith to faith - from Old Testament faith in a Christ to come to New Testament faith in a Christ already come."
