Such a disposition is not altogether a matter of temperament, but may be cultivated, and though it may come easier to some of us than to others, it certainly ought to belong to all who have God to trust to, and believe that the gospel is His truth. They may well be strong who have Divine power ready to flood their hearts, who know that everything works for their good, who can see, above the whirl of time and change, one strong loving Hand which moves the wheels. What have we to do with fear for ourselves, or wherefore should our "hearts tremble for the ark of God," seeing that One fights by our sides who will teach our hands to war and cover our heads in the day of battle? "Be of good courage, and He shall strengthen thine heart." (2) The way to secure such joyous confidence and strength is taught us here, for we have next, _Union in love_, as part of the means for obtaining it--"They being knit together in love." The persons, not the hearts, are to be thus united. Love is the true bond which unites men--the bond of perfectness, as it is elsewhere called. That unity in love would, of course, add to the strength of each. The old fable teaches us that little fagots bound together are strong, and the tighter the rope is pulled, the stronger they are. A solitary heart is timid and weak, but many weaknesses brought together make a strength, as slimly built houses in a row hold each other up, or dying embers raked closer burst into flame. Loose grains of sand are light and moved by a breath; compacted they are rock against which the Atlantic beats in vain. So, a Church, of which the members are bound together by that love which is the only real bond of Church life, presents a front to threatening evils through which they cannot break. A real moral defence against even intellectual error will be found in such a close compaction in mutual Christian love. A community so interlocked will throw off many evils, as a Roman legion with linked shields roofed itself over against missiles from the wall of a besieged city, or the imbricated scales on a fish keep it dry in the heart of the sea. But we must go deeper than this in interpreting these words. The love which is to knit Christian men together is not merely love to one another, but is common love to Jesus Christ. Such common love to Him is the true bond of union, and the true strengthener of men's hearts. (3) This compaction in love will lead to a wealth of certitude in the possession of the truth.
