Among all examples of calling, only Cornelius the centurion was called because his prayer and alms had come up to God.
But that was a special, providential case, preparing the way for the reception into the bosom of the Church of sheep who were not of the fold of Israel.
The general order of calling is the work of goodness, in the beginning, now, and to the end of the age.
One must, however, strictly distinguish the calling to salvation already ordered from the accomplishment of salvation by the manner in which it has been ordered.
From the moment one heeds the calling and takes the first step according to it, one's own labor and effort already begin to participate in the accomplishment of salvation.
This labor goes hand in hand with grace until the final accomplishment of salvation itself. Everything is from goodness, but God's goodness is not indulgent.
"But according to His mercy He saved us by the laver of regeneration." He says this not as one looking at the salvation of others, but as one who himself has received salvation.
In the feeling of salvation he proclaims with grateful lips: "He saved." From what did He save us? From all the wretched things discussed above, and from slavery to passions and pleasures.
We groaned under that yoke. "He saved us." Whom does "us" mean? All who have believed in the Lord Jesus Christ.
"By naming himself and the Apostles, St. Paul meant all who have believed in Christ, showing what they were before regeneration in the life-giving laver, and what they became afterward" (Blessed Jerome).
How did He save? "By the laver of regeneration and renewal of the Holy Spirit."
"Alas!" cries St. Chrysostom. "We were so deeply immersed in evil that we could no longer be cleansed, but had need of regeneration.
This truly was a new birth, the receiving of a new being. No one puts a prop under a rotten house or fastens something onto an old building.
Rather, he tears it down to the foundation, then raises and renews it entirely. So also He, our Savior, acted. He did not repair us, but recreated us entirely.
This is what the words 'and renewal of the Holy Spirit' mean. He made us entirely new. How? By the Holy Spirit. So great is our need of grace!"
