I have sometimes thought there could be no stronger testimony in favor of Religion or against temporal Enjoyments even the most rational and manly than for men who occupy the most honorable and gainful departments and are rising in reputation and wealth, publicly to declare their unsatisfactoriness by becoming fervent Advocates in the cause of Christ, & I wish you may give in your Evidence in this way. Such instances have seldom occurred, therefore they would be more striking and would be instead of a "Cloud of Witnesses."
