19. But we will not now remark further upon this subject. To return to Peter: He admonishes us to be sober so that we may give ourselves to prayer, as becometh those who are Christians and have turned from the vile, heathenish conduct of the world. Just preceding our text, in verse 3, he says: "For the time past may suffice to have wrought the desire of the Gentiles, and to have walked in lasciviousness, lusts, winebibbings, revellings, carousings, and abominable idolatries." He admonishes us as being now called and ordained to contend against the devil by faith and prayer. Later on (ch. 5, 8) he brings in the same warning in clearer phrase, exhorting Christians to be sober and watchful. Do you ask, What is the great necessity therefor? he says: "Your adversary the devil, as a roaring lion [in the midst of a flock of sheep], walketh about, seeking whom he may devour." Peter's meaning is this: Since you are a people called to contend with this powerful spirit which is more intent on seizing your souls than is the wolf on seizing the sheep, it is essential you should take thought how to withstand him. Resistance is effected only through faith and prayer. But soberness and vigilance are necessary to enable one to pray. With gormandizers and drunkards, reason is dethroned and they are rendered incapable of respecting anything, or of performing any good work. Therefore, the ability to pray and call upon God has been taken from them and the devil overcomes and devours them at his will. 20. The diligence in prayer which characterized Christians of the primitive Church, even while undergoing great persecution, is apparent to us. They were more than willing to assemble daily for prayer together, not only morning and evening, but also at certain other appointed hours; and frequently they watched and prayed entire nights. Some of them, according to St. Augustine, carried their vigils to such extent as at times to abstain from food for four days. True, this was going to somewhat of an extreme, particularly when later the practice came to be an example and a commandment. Yet their habit of perfect sobriety morning, evening and at all times is commendable. With the cessation of this practice in the congregations, there succeeded the wretched order of monks, who pretend to do the praying for others. They, it is true, observed the same appointed hours, the same seasons of prayer, in their matins, vespers, and so on, but they did not really pray; they merely kept up an incessant sound, muttering and howling. We still retain from the ancient custom the observance of morning and evening prayers in schools for children. But the same practice should obtain in every Christian family. Every father is under obligation to train up his children to pray at least at the beginning and the close of day, commending to God every exigency of this earthly life, that God's wrath may be averted, and deserved punishment withheld.
