Paul's love for the Thessalonians did not blind him to their imperfections. It was their faith which comforted him in all his distress, yet he speaks of the deficiencies of their faith as something he sought to remedy. In one sense, faith is a very simple thing, the setting of the heart right with God in Christ Jesus. In another, it is very comprehensive. It has to lay hold on the whole revelation which God has made in His Son, and it has to pass into action through love in every department of life. It is related on the one side to knowledge, and on the other to conduct. Now Timothy saw that while the Thessalonians had the root of the matter in them, and had set themselves right with God, they were far from perfect. They were ignorant of much which it concerned Christians to know; they had false ideas on many points in regard to which God had given light. They had much to do before they could be said to have escaped from the prejudices, the instincts, and the habits of heathenism, and to have entered completely into the mind of Christ. In later chapters we shall find the Apostle rectifying what was amiss in their notions both of truth and duty; and, in doing so, opening up to us the lines on which defective faith needs to be corrected and supplemented. But we should not pass by this notice of the deficiencies of faith without asking ourselves whether our own faith is alive and progressive. It may be quite true and sound in itself; but what if it never gets any further on? It is in its nature an engrafting into Christ, a setting of the soul into a vital connection with Him; and if it is what it should be, there will be a transfusion, by means of it, of Christ into us. We shall get a larger and surer possession of the mind of Christ, which is the standard both of spiritual truth and of spiritual life. His thoughts will be our thoughts; His judgment, our judgment; His estimates of life and the various elements in it, our estimates; His disposition and conduct, the pattern and the inspiration of ours. Faith is a little thing in itself, the smallest of small beginnings; in its earliest stage it is compatible with a high degree of ignorance, of foolishness, of insensibility in the conscience; and hence the believer must not forget that he is a disciple; and that though he has entered the school of Christ, he has only entered it, and has many classes to pass through, and much to learn and unlearn, before he can become a credit to his Teacher. An Apostle coming among us would in all likelihood be struck with manifest deficiencies in our faith. This aspect of the truth, he would say, is overlooked; this vital doctrine is not really a vital piece of your minds; in your estimate of such and such a thing you are betrayed by worldly prejudices that have survived your conversion; in your conduct in such and such a situation you are utterly at variance with Christ. He would have much to teach us, no doubt, of truth, of right
