Whether we ought to ask for something definite when we pray?

Objections

Objection 1 : It would seem that we ought not to ask for anything definite when we pray to God. According to Damascene (De Fide Orth. iii, 24), "to pray is to ask becoming things of God"; wherefore it is useless to pray for what is inexpedient, according to James 4:3, "You ask, and receive not: because you ask amiss." Now according to Rm. 8:26, "we know not what we should pray for as we ought." Therefore we ought not to ask for anything definite when we pray.
Objection 2 : Further, those who ask another person for something definite strive to incline his will to do what they wish themselves. But we ought not to endeavor to make God will what we will; on the contrary, we ought to strive to will what He wills, according to a gloss on Ps. 32:1, "Rejoice in the Lord, O ye just." Therefore we ought not to ask God for anything definite when we pray.
Objection 3 : Further, evil things are not to be sought from God; and as to good things, God Himself invites us to take them. Now it is useless to ask a person to give you what he invites you to take. Therefore we ought not to ask God for anything definite in our prayers.
