and through our deficiency in insulation, or, which is the same word, in isolation. If we go into a science laboratory and examine the great brass machines for holding electrical charges, we find that they are all mounted on glass feet. These are the insulators, and if it were not for them, no electricity would remain on the surface; as it is, electricity is hard enough to keep in charge, even with the best insulators. And we know sometimes what it is to have life and power pass into us from above, but we don't know how to retain it, because we have never learnt true retirement of heart and insulation of life. There is good teaching in the following passage from one of Madame Guyon's letters: "It is very desirable, and in the earlier part of your ministry especially, that you should spend a portion of your time--and that perhaps not a small portion--with God in retirement. Let your own soul be first filled with God's spirit, and then and not otherwise will you be in a situation to communicate the Divine fulness to others. No man can give what he has not; or if a man has grace, but has it in a small degree, he may in dispensing to others impart to them what is necessary for himself." Now if any one were to ask what is the especial strength of England as regards other empires and commonwealths, the answer would be that it lies in her insular position,--in the "silver streak" that parts her from France; and the true Christian is girt round with separating grace. We might draw two pictures to remind us how we may become strong for God: one of the solitary vigil of the Great Shepherd keeping watch over His flock by night; the other of the little company who waited with joined hands and hearts in the upper room for the coming of the Comforter; these two pictures representing the solitude of a single soul and of united souls with God. By such silent communion God will especially prepare us for service and for suffering. Some one spoke to John Nelson, making unfavourable comparison of John Wesley with a prominent religious teacher of the day; and Nelson replied, "He has not stayed in the upper room like John Wesley." We need our silent preparations for speech; to go forth, like Ezekiel, into the plain to find the glory of the Lord; or like Daniel to the river-side, where we may meet one like unto the Son of man; or like the two who walked into the country whom Jesus met, and with whom He talked till He made their hearts burn.
