"Only one lease on life is granted us; Every man has the oppurtunity ...of making himself whaterver he chooses. He may build up a character of solid worth,...He may advance daily in knowledge and wisdom, ...adding virtue to virtue, grace to grace. On the other hand, he may allow his powers to rust out, or to be perverted through evil habits. Appetite conquers him. It is easier for him to allow the powers of evil to draw him backwards, than to struggle against them, and go forward. Dissipation, disease and death follow. This is the history of many lives that might have been useful in the cause of God and humanity."
Counsels on Diet & Foods p.15,16 E.G.W
....only if they will observe to do according to all that I have commanded them, and
according to all the law that my servant Moses commanded them.
