Whether Christ's prayer was always heard?

Objections

Objection 1 : It would seem that Christ's prayer was not always heard. For He besought that the chalice of His passion might be taken from Him, as we read (Mt. 26:39): and yet it was not taken from Him. Therefore it seems that not every prayer of His was heard.
Objection 2 : Further, He prayed that the sin of those who crucified Him might be forgiven, as is related (Lk. 23:34). Yet not all were pardoned this sin, since the Jews were punished on account thereof. Therefore it seems that not every prayer of His was heard.
Objection 3 : Further, our Lord prayed for them "who would believe in Him through the word" of the apostles, that they "might all be one in Him," and that they might attain to being with Him (Jn. 17:20,21,24). But not all attain to this. Therefore not every prayer of His was heard.
Objection 4 : Further, it is said (Ps. 21:3) in the person of Christ: "I shall cry by day, and Thou wilt not hear." Not every prayer of His, therefore, was heard.
