“What are you doing, brethren, in the great work of preparation? Those who are uniting with the world are receiving the worldly mold and preparing for the mark of the beast. Those who are distrustful of self, who are humbling themselves before God and purifying their souls by obeying the truth—these are receiving the heavenly mold and preparing for the seal of God in their foreheads. When the decree goes forth and the stamp is impressed, their character will remain pure and spotless for eternity. Now is the time to prepare.” 5T 216.1
