Build your nest upon no tree here, for you see God hath sold the forest to death; and every tree whereupon we would rest is ready to be cut down, to the end we may flee and mount up, and build upon the rock, and dwell in the holes of the rock...... There is less sand in your glass now than there was yesternight; this span length of ever-changing time will soon be ended; but the greater is the mercy of God, the more years you get to advise upon what terms and upon what conditions you east your soul into the huge gulf of never-ending eternity.” —Rutherford’s Letters.
