1:12-15 We must be established in the belief of the truth, that we may not be shaken by every wind of doctrine; and especially in the truth necessary for us to know in our day, what belongs to our peace, and what is opposed in our time. The body is but a tabernacle, or tent, of the soul. It is a mean and movable dwelling. The nearness of death makes the apostle diligent in the business of life. Nothing can so give composure in the prospect, or in the hour, of death, as to know that we have faithfully and simply followed the Lord Jesus, and sought his glory. Those who fear the Lord, talk of his loving-kindness. This is the way to spread the knowledge of the Lord; and by the written word, they are enabled to do this.
14. shortly I must put off—Greek, "the putting off (as a garment) of my tabernacle is speedy": implying a soon approaching, and also a sudden death (as a violent death is). Christ's words, Joh 21:18, 19, "When thou art old," &c., were the ground of his "knowing," now that he was old, that his foretold martyrdom was near. Compare as to Paul, 2Ti 4:6. Though a violent death, he calls it a "departure" (Greek for "decease," 2Pe 1:15), compare Ac 7:60.
