Again I say unto you. The following paragraph has been thought by many to be addressed especially to the apostles in confirmation of the powers conferred on them above; but from Matthew 18:20 we should judge the promise to be general.
Herein is set forth the privilege of united prayer. God confirms the sentence of his authorized ambassadors; he gives special heed to the joint intercessions of all Christians. Two of you. Two of my followers, even the smallest number that could form an association.
Shall agree ( συμφωνη ìσωσιν). Be in complete accord, like the notes of a perfect strain of music. Here one man's infirmity is upheld by another's strength; one man's short-sightedness compensated by another's wider view; this man's little faith overpowered by that man's firm confidence.
Anything. Of course, this is to be understood with some restriction. The thing asked must be reasonable, good in itself, expedient for the petitioner; the prayer must be earnest, faithful, persevering.
If such conditions are satisfied, the desire will be granted in some form, though, perhaps, not in the way or at the time expected. Thus the Lord sanctions guilds or bodies of Christians united together to offer up supplications for special objects or with some definite intention in which all ere agreed.
