Job Chapter 13
(Job 13:1-12) Job reproves his friends.
(Job 13:13-22) He professes his confidence in God.
(Job 13:23-28) Job entreats to know his sins.
With self-preference, Job declared that he needed not to be taught by them. Those who dispute are tempted to magnify themselves, and lower their brethren, more than is fit. When dismayed or distressed with the fear of wrath, the force of temptation, or the weight of affliction, we should apply to the Physician of our souls, who never rejects any, never prescribes amiss, and never leaves any case uncured. To Him we may speak at all times. To broken hearts and wounded consciences, all creatures, without Christ, are physicians of no value. Job evidently speaks with a very angry spirit against his friends. They had advanced some truths which nearly concerned Job, but the heart unhumbled before God, never meekly receives the reproofs of men.
Job resolved to cleave to the testimony his own conscience gave of his uprightness. He depended upon God for justification and salvation, the two great things we hope for through Christ. Temporal salvation he little expected, but of his eternal salvation he was very confident; that God would not only be his Saviour to make him happy, but his salvation, in the sight and enjoyment of whom he should be happy. He knew himself not to be a hypocrite, and concluded that he should not be rejected. We should be well pleased with God as a Friend, even when he seems against us as an enemy. We must believe that all shall work for good to us, even when all seems to make against us. We must cleave to God, yea, though we cannot for the present find comfort in him. In a dying hour, we must derive from him living comforts; and this is to trust in him, though he slay us.
Job begs to have his sins discovered to him. A true penitent is willing to know the worst of himself; and we should all desire to know what our transgressions are, that we may confess them, and guard against them for the future. Job complains sorrowfully of God's severe dealings with him. Time does not wear out the guilt of sin. When God writes bitter things against us, his design is to make us bring forgotten sins to mind, and so to bring us to repent of them, as to break us off from them. Let young persons beware of indulging in sin. Even in this world they may so possess the sins of their youth, as to have months of sorrow for moments of pleasure. Their wisdom is to remember their Creator in their early days, that they may have assured hope, and sweet peace of conscience, as the solace of their declining years. Job also complains that his present mistakes are strictly noticed. So far from this, God deals not with us according to our deserts. This was the language of Job's melancholy views. If God marks our steps, and narrowly examines our paths, in judgment, both body and soul feel his righteous vengeance. This will be the awful case of unbelievers, yet there is salvation devised, provided, and made known in Christ.
