Therefore say thou - Literally, “And thou sayest,” that is, this having been so, it follows that thou sayest or must say, “Turn ye unto Me.” In some degree they had turned to God, for whose sake they had returned to their land; and again when, after some negligence Haggai 1:2-11, they renewed the building of the temple, and God had said, “I am with you” Haggai 1:13. But there needed yet a more inward, more complete turning, whereon God promises a yet nearer presence, as Malachi repeats the words Malachi 3:7, and James exhorts, “Draw nigh to God and He will draw nigh to you” James 4:8. Those who have turned to God need ever to turn more into the center of the narrow way. As the soul opens itself more to God, God, whose communication of Himself is ever hindered only by our closing the door of our hearts against Him, enters more into it. “If a man love Me, he will keep My words, and My Father will love him, and We will come unto him, and make Our abode with him” John 14:23.
Osorius: “People are said to be converted, when leaving behind them deceitful goods, they give their whole mind to God, bestowing no less pains and zeal on divine things than before on the nothings of life.”
Conc. Trid. Sess. vi. c. 5: “When it is said in Holy Scripture, “Turn unto Me and I will turn unto you,” we are admonished as to our own freedom; when we answer, “Turn us, Lord, unto Thee, and we shall be turned,” we confess that we are forecome by the grace of God.”
