“The unsoundness of a vessel is not seen when it is empty, but when it is filled with water, then we shall see whether it will leak or no.   It is in our prosperity that we are tested.  Men are not fully discovered to themselves till they are tried by fullness of success.  Praise finds the crack of pride, wealth reveals the flaw of selfishness, and learning discovers the leak of unbelief.  David’s besetting sin was little seen in the cracks of the wild goats, but it became conspicuous upon the terrace of his palace.  Success is the crucible of character.  Hence the prosperity which some welcome as an unmixed favor may far more rightly be regarded as an intense test.  O Lord, preserve us when we are full as much as when we are empty.”  C. H. Spurgeon
