Bede : And this is the confidence that we have toward him, etc. He provides us with great confidence to hope for heavenly goods from the Lord, because even in this life, whatever we ask of him in a salutary manner, we obtain, according to what he himself promises believers in the Gospel: "I say to you, whatever you ask in prayer, believe that you have received it, and it will be yours" (Mark XI). But it must be noted that we are heard by the Lord when praying in such a way, provided we ask for what he has commanded. He himself says, "Seek first the kingdom of God and his righteousness" (Matthew VI). Hence, John rightly interposed after saying, "Whatever we ask, we receive from him," by adding, "according to his will." Therefore, we are commanded to have full and undoubted confidence of being heard only regarding those things which align not with our own benefits or temporal comforts but with the Lord's will. This is also to be included in the Lord's Prayer: "Your will be done" (Matthew VI), that is, not ours. For if we remember the Apostle's words: "For we do not know what to pray for as we ought" (Romans VIII), we understand that sometimes we ask for things contrary to our own salvation, and it is most beneficial for us that those things we ask are denied by him who perceives our benefit more rightly than we do. This undoubtedly happened even to the teacher of the Gentiles himself. — Commentary on the Catholic Epistles Clement of Alexandria ((as quoted by Cassiodorus)) : "And this is the confidence which we have towards Him, that if we ask anything according to His will, He will hear us." He does not say absolutely what we shall ask, but what we ought to ask. — From the Latin Translation of Cassiodorus Didymus the Blind : Those who possess technical skills and know how to repair things are fully confident that when the need arises they will be able to do so. Similarly these holy men, John and the other apostles, knew from their own experience that if they asked God for what was pleasing and acceptable to him, they would obtain it. For God is most generous to those who have this knowledge and will grant the requests of those who ask according to his will. — COMMENTARY ON 1 JOHN Oecumenius : And this is the confidence that we have in Him, that if we ask anything according to His will, He hears us. And if we know that He hears us in whatever we ask, we know that we have the requests that we have asked of Him. Then, since there is no other sign of this unquestionable faith except trust, which we find in Him through irreproachable faith, as we have also said before. Again, He has set a sign of this trust, that we are not to be frustrated in all that is asked of us. But since not everyone achieves all that they ask for, nor are they always heard in what they request, He adds: according to His will: revealing indeed that the one asking, outside the will of the Master, is not to be heard, in accordance with blessed James: for he also said, "You ask and do not receive, because you ask with wrong motives," (James 4:3) that is, as it does not benefit you. However, converting this sign into a clearer indication, John says: "And if we know that He hears us in whatever we ask, we know that we have the requests that we have asked of Him:" saying something like this: If we ask according to His will, He hears us: and if He hears us in whatever we ask, we know that we make our requests according to His will, and we have in ourselves the requests that we have asked. These, however, are His kingdom and righteousness (Matt. 6:33): which He also commanded us to ask for. Having said this, He also clearly proposes something of what He wants us to ask according to God's will. For the entire letter is largely about extolling love for the brother and expressing the desire that we keep our love for the brother incorrupt, John now says that this is one of his wills, that "if anyone sees his brother sinning not unto death, he should ask, and it will be given to him." (1 Jn. 5:16) And what will be given? "Eternal life." To whom? "Those who sin not unto death." — Commentary on 1 John
