Jesus answered her, "If you knew the gift of God, and who it is who says to you, 'Give me a drink,' you would have asked him, and he would have given you living water."
If thou knewest the gift of God. These two clauses, If thou knewest the gift of God, and, who it is that talketh with thee, I read separately, viewing the latter as an interpretation of the former. For it was a wonderful kindness of God to have Christ present, who brought with him eternal life. The meaning will be more plain if, instead of and, we put namely, or some other word of that kind, (75) thus: If thou knewest the gift of God, namely,who it is that talketh with thee By these words we are taught that then only do we know what Christ is, when we understand what the Father hath given to us in him, and what benefits he brings to us. Now that knowledge begins with a conviction of our poverty; for, before any one desires a remedy, he must be previously affected with the view of his distresses. Thus the Lord invites not those who have drunk enough, but the thirsty, not those who are satiated, but the hungry, to eat and drink. And why would Christ be sent with the fullness of the Spirit, if we were not empty?
