As Governor of Massachusetts, Samuel Adams wrote to James Warren, February 12, 1779:
A general dissolution of the principles and manners will more surely overthrow the liberties of America than the whole force of the common enemy. While the people are virtuous they cannot be subdued; but once they lose their virtue, they will be ready to surrender their liberties to the first external or internal invader… If we would enjoy this gift of Heaven, let us become a virtuous people.
Amen Mr. Adams. To that I would add:
Except the LORD build the house, they labour in vain that build it: except the LORD keep the city, the watchman waketh but in vain. It is vain for you to rise up early, to sit up late, to eat the bread of sorrows: for so He giveth His beloved sleep. — from Psalm 127
And it shall come to pass, if thou shalt hearken diligently unto the voice of the LORD thy God, to observe and to do all His commandments which I command thee this day, that the LORD thy God will set thee on high above all nations of the earth: And all these blessings shall come on thee, and overtake thee, if thou shalt hearken unto the voice of the LORD thy God. Blessed shalt thou be in the city, and blessed shalt thou be in the field. Blessed shall be the fruit of thy body, and the fruit of thy ground, and the fruit of thy cattle, the increase of thy kine, and the flocks of thy sheep. Blessed shall be thy basket and thy store. Blessed shalt thou be when thou comest in, and blessed shalt thou be when thou goest out. The LORD shall cause thine enemies that rise up against thee to be smitten before thy face: they shall come out against thee one way, and flee before thee seven ways. — from Deuteronomy 28
