If by "faith" you mean "religious belief," then "yes." I have changed my beliefs many times over the years as I have learned new things.
Most religious belief is interpretation, and interpretation is subject to flaws.
And finding Truth is like finding a needle in a haystack. So much of the hay is confusion, misinterpretation and misdirection.
Important question that guides me: "Is my interpretation equal to that of God's?" And certainly it isn't, so I remain humble and continue searching.
When I can walk on water, then I may be close, but only if I can maintain utter humility while doing it.
