Thomas Boston, Works, 5:225-226:
The friendship of many in the world is no more but an empty name: if a good word will serve their friend, they will give it him; but for any good deed, it is far from them, James 2:16. Yea, the friendship of many is destructive; it serves for nothing but to be a snare, a trap, and a bond of iniquity, James 4:4; as between Herod and Pilate. But Christ’s friendship is most beneficial: it is enriching and upmaking. The benefits of it who can tell? They will tell out for time and eternity; they are for the soul and for the body. One needs no more to make him happy: they are for prosperity, and for adversity.
