The following is the results of your search for proportion of faith.
Proportion of Faith: (Romans 12:6) Paul says here that each one was to exercise his gift of
prophecy, i.e., of teaching, "according to the proportion of faith."
The meaning is, that the utterances of the "prophet" were not to
fluctuate according to his own impulses or independent thoughts, but
were to be adjusted to the truth revealed to him as a beliver, i.e.,
were to be in accordance with it. In post-Reformation times this
phrase was used as meaning that all Scripture was to be interpreted
with reference to all other Scripture, i.e., that no words or
expressions were to be isolated or interpreted in a way contrary to
its general teaching. This was also called the "analogy of faith."
