There is no obligation for the Superior to show this grace. It is totally dependent on His generosity.
For Paul the grace of God is not so much a timeless attribute as an activity of God. It is the redeeming activity of God that manifests itself in the redemptive work of Christ by which sinners are forgiven and accepted by God. In Paul's thought the grace of God is necessary because of man's total inability to do anything to save himself and because of man's unworthiness to be saved. Paul's use of grace to refer to the undeserved nature of God's salvation was particularly illustrated by his own experience. His former life as a persecutor of Christians caused him to have a profound sense of his own unworthiness. it was only because of the grace of God that Christ appeared to him, changed him, and appointed him to be an Apostle [1 Cor. 15:9-10; 1 Tim. 1:12-14]. So pervasive was Paul's sense of grace that he refers to it at the beginning and end of every one of his letters [now I know why].
Salvation from beginning to the end is all of Grace. There can be no mixture of grace and works, or else it would not be grace [Rom. 11:6-7].
In the OT is the translation of the Hebrew noun chen and the verb chanan===be favorable or merciful. It refers to the kind turning of either God or humans to persons in an act of assistance in time of need [Prov. 14:3; Ps. 4:1]. The noun chen "Grace" or "favor" without any apparent difference in the two. The most significant use of "grace" in the OT is to express a divine/human relationship.
