FAITH IS EASY, WISDOM IS HARD
The title of this page says it all. Faith is easy. It is wisdom which is SOMETIMES hard to obtain. II Peter 3:16 says:
As also in all his epistles, speaking in them of these things; in which are some things hard to be understood, which they that are unlearned and unstable wrest, as they do also the other Scriptures, unto their own destruction.
Notice the words “some things hard to be understood.” There is some wisdom that is hard to come by.
