Reply Obj. 1: Although man cannot by himself know what he ought to pray for, "the Spirit," as stated in the same passage, "helpeth our infirmity," since by inspiring us with holy desires, He makes us ask for what is right. Hence our Lord said (John 4:24) that true adorers "must adore . . . in spirit and in truth."
Reply Obj. 2: When in our prayers we ask for things concerning our salvation, we conform our will to God's, of Whom it is written (1 Tim. 2:4) that "He will have all men to be saved."
Reply Obj. 3: God so invites us to take good things, that we may approach to them not by the steps of the body, but by pious desires and devout prayers. _______________________
SIXTH ARTICLE [II-II, Q. 83, Art. 6]
Whether Man Ought to Ask God for Temporal Things When He Prays?
Objection 1: It would seem that man ought not to ask God for temporal things when he prays. We seek what we ask for in prayer. But we should not seek for temporal things, for it is written (Matt. 6:33): "Seek ye . . . first the kingdom of God, and His justice: and all these things shall be added unto you," that is to say, temporal things, which, says He, we are not to seek, but they will be added to what we seek. Therefore temporal things are not to be asked of God in prayer.
Obj. 2: Further, no one asks save for that which he is solicitous about. Now we ought not to have solicitude for temporal things, according to the saying of Matt. 6:25, "Be not solicitous for your life, what you shall eat." Therefore we ought not to ask for temporal things when we pray.
Obj. 3: Further, by prayer our mind should be raised up to God. But by asking for temporal things, it descends to things beneath it, against the saying of the Apostle (2 Cor. 4:18), "While we look not at the things which are seen, but at the things which are not seen. For the things which are seen are temporal, but the things which are not seen are eternal." Therefore man ought not to ask God for temporal things when he prays.
Obj. 4: Further, man ought not to ask of God other than good and useful things. But sometimes temporal things, when we have them, are harmful, not only in a spiritual sense, but also in a material sense. Therefore we should not ask God for them in our prayers.
On the contrary, It is written (Prov. 30:8): "Give me only the necessaries of life."
