Psalm 133:1 Behold, how good and pleasant it is
when brothers dwell in unity!
In John 17, Jesus prays for us as believers to have this unity, that we should be one. And in Acts 4:32, we read that, “Now the full number of those who believed were of one heart and soul.”
As in music, though there be several strings of a viol, yet all make one sweet harmony; so, though there are several Christians, yet there should be one sweet harmony of affection among them. There is but one God, and they that serve him should be one. There is nothing that would render the true religion more lovely, or make more proselytes to it, than to see the professors of it tied together with the heart strings of love. If God be one, let all that profess him be of one mind, and one heart, and thus fulfill Christ’s prayer, “that they all may be one.”
