All the cases down:
. . . They can know but little . . . of that happiness which God has prepared for them that love him; but . . . this suffices them, that they shall see him as he is, etc. . . . the expectation founded upon his own gracious promise, etc.—Rev. John Newton’s Sermon on the “happy recovery” of King George (modern reprint).
But, whatever the style of the office, there is one category in which the personal pronoun must be capitalized: it is when no antecedent is expressed. Such cases are not of infrequent occurrence. If one were to write—
In all her troubles this good lady never failed to express her confidence in the care of him in whom she had put her trust—
the meaning would be doubtful; “him” might refer to some humane relative, or to the superintendent of the almshouse. But if the sentence were written—
. . . this good lady never failed to express her confidence in the care of Him in whom, etc.—
the meaning—that the Deity is intended—becomes clear.
Adjuncts qualifying names applied to Deity usually require no capitals:
For when we consider ourselves as the creatures of God . . . what can induce us to love, fear, and trust Him, as our God, our Father, and all-sufficient Friend and Helper.—
Mason’s Self-Knowledge.
