All blessings are divine in origin, but none can be compared with this power of intellectual investigation and research, which is an eternal gift producing fruits of unending delight. Man is ever partaking of these fruits. All other blessings are temporary; this is an everlasting possession. Even sovereignty has its limitations and overthrow; this is a kingship and dominion which none may usurp or destroy. Briefly, it is an eternal blessing and divine bestowal, the supreme gift of God to man.
