And all things, whatsoever you shall ask in prayer, believing, you shall receive.
All Commentaries on Matthew 21:22 Go To Matthew 21
Theophylact of Ochrid
Great is the promise which Christ makes to His disciples, the ability to move mountains, if only we are not ambiguous in faith, that is, we do not hesitate. Whatever we ask, unhesitantly believing in God’s power, we shall receive. One might ask, "And if I ask for something unprofitable, and foolishly believe that God will give me this, will I indeed receive this unprofitable thing? How is it that God is said to love mankind if He would fulfill my unprofitable request?" Listen then. First, when you hear "faith," you should understand that it means not "foolish faith" but "true faith"; and when you hear "prayer," understand it to mean that prayer which asks for things profitable, such as the Lord gave to us when He said, "Lead us not into temptation but deliver us from the evil one," and petitions of similar nature. Then consider the words "doubt not," [literally, "be ye not divided," me diakrithete]. For how could a man who is united with God as one and not divided or separated from Him, how could that man ask for something unprofitable? So if you are undivided and inseparable from God, then you will ask for and receive things which are profitable for you.
