“Faith is the assured expectation of things hoped for, the evident demonstration of realities though not beheld.” (Heb. 11:1) True faith is not credulity, that is, a readiness to believe something without sound evidence or just because a person wants it to be so.
Genuine faith requires basic or fundamental knowledge, acquaintance with evidence, as well as heartfelt appreciation of what that evidence indicates. Thus, although it is impossible to have real faith without accurate knowledge, the Bible says that it is “with the heart” that one exercises faith.—Rom. 10:10.
