Isaac Watts

Some persons believe everything that their kindred, their parents, and their tutors believe. The veneration and the love which they have for their ancestors incline them to swallow down all their opinions at once, without examining what truth or falsehood there is in them. Men take their principles by inheritance, and defend them as they would their estates, because they are born heirs to them.

F. W. Robertson

It is not the number of books you read, nor the variety of sermons you hear, nor the amount of religious conversation in which you mix, but it is the frequency and earnestness with which you meditate on these things until the truth in them becomes your own and part of your being, that ensures your growth.
