Psalms 70:6

Then again one might inquire at what time those who are called their angels assume guardianship of the little ones pointed out by Christ; whether they received this commission to discharge concerning them, from what time “by the laver of regeneration,” through which they were born “as new-born babes, they long for the reasonable milk which is without guile,” and no longer are in subjection to any wicked power; or, whether from birth they had been appointed, according to the foreknowledge and predestination of God, over those whom God also foreknew, and foreordained to be conformed to the glory of the Christ. …

7. Lastly, there followeth the reason why I say this: “for Thou art my patience” ( ver. 5 ). Now if He is patience rightly, He is that also which followeth, “O Lord, my hope from my youth.” My patience, because my hope: or rather my hope, because my patience. “Tribulation,” saith the Apostle, “worketh patience, patience probation, but probation hope, but hope confoundeth not.” With reason in Thee I have hoped, O Lord, I shall not be confounded for everlasting. “O Lord, my hope from my youth.” From thy youth is God thy hope? Is He not also from thy boyhood, and from thine infancy? Certainly, saith he. …

10. My hope from my youth, “cast me not away in time of old age” ( ver. 9 ). What is this time of old age? “When my strength shall fail, forsake Thou not me.” Here God maketh this answer to thee, yea indeed let thy strength fail, in order that in thee mine may abide: in order that thou mayest say with the Apostle, “When I am made weak, then I am mighty.” Fear not, that thou be cast away in that weakness, in that old age. But why? Was not thy Lord made weak on the Cross? Did not most mighty men and fat bulls before Him, as though a man of no strength, made captive and oppressed, shake the head and say, “If Son of God He is, let Him come down from the Cross”? Has he deserted because He was made weak, who preferred not to come down from the Cross, lest He should seem not to have displayed power, but to have yielded to them reviling? What did He hanging teach thee, that would not come down, …

11. In the same manner it may also be said of the word “in,” that Scripture admits its use in the case of God the Father. In the Old Testament it is said through ( ἐν ) God we shall do valiantly, and, “My praise shall be continually of ( ἐν ) thee;” and again, “In thy name will I rejoice.” In Paul we read, “In God who created all things,” and, “Paul and Silvanus and Timotheus unto the church of the Thessalonians in God our Father;” and “if now at length I might have a prosperous journey by ( ἐν ) the will of God to come to you;” and, “Thou makest thy boast of God.” Instances are indeed too numerous to reckon; but what we want is not so much to exhibit an abundance of evidence as to prove that the conclusions of our opponents are unsound. I shall, therefore, omit any proof of this usage in the case of our Lord and of the Holy Ghost, in that it is notorious. …

76. But let them learn that it is also said of God the Father: “In the Lord I will praise the word;” and elsewhere: “In God we will do mighty deeds;” and “My remembrance shall be ever in Thee;” and “In Thy Name will we rejoice;” and again in another place: “That his deeds may be manifested, that they are wrought in God;” and Paul: “In God Who created all things;” and again: “Paul and Silvanus and Timotheus to the Church of the Thessalonians in God the Father and the Lord Jesus Christ;” and in the Gospel: “I in the Father and the Father in Me,” and “the Father that dwelleth in Me.” It is also written: “He that glorieth let him glory in the Lord;” and in another place: “Our life is hid with Christ in God.” Did he here ascribe more to the Son than to the Father in saying that we are with Christ in God? or does our state avail more than the grace of the Spirit, so that we can be with Christ …
