Christ and drawing upon His help, is to be our shield, off which the enemy's darts will glance harmless, their hurtful fire quenched. And in thus defending ourselves we must have continually in mind that God has delivered man by a great redemption[8]. It is the sense of this great salvation, the conviction of each Christian that he is among those who have been saved and are tasting this salvation, which is to cover his head from attack like a helmet[9]. And God's {245} word--God's specific and particular utterances, through inspired prophets and psalmists--is to equip his mouth with a sword of power; as in His temptation and on the cross, Christ 'put off from Himself the principalities and powers, and made a show of them, triumphing over them openly' by the words of Holy Scripture; as Bunyan's Christian, when 'Apollyon was fetching him his last blow, nimbly stretched out his hand and caught' for his 'sword' the word of Micah, 'when I fall I shall arise.' This is one fruit of constant meditation on the words of Holy Scripture, that they recur to our minds when we most need them. And then St. Paul passes from metaphor to simple speech, and for the last weapon bids the Christians use 'always' that most powerful of all spiritual weapons for themselves and others, 'prayer and supplication' of all kinds and 'in all seasons.' But it is not to be ignorant and blind prayer; it is to be prayer 'in the spirit,' 'who helpeth our infirmities, for we know not of ourselves how to pray as we ought.' 'The things of God none knoweth, save the Spirit of God'[10]; and it is to be the sort of prayer about which trouble is taken, and which is persevering; and it is to be {246} prayer for others as well as for themselves, 'for all the saints.' And St. Paul uses the pastor's privilege, and asks for himself the support of his converts' prayers, that he may have both power of speech and courage to proclaim the good tidings of the divine secret disclosed, for which he is already suffering as a prisoner.
