Verses 7, 8

The Apostle, seeing the excellency of that which had been given to him, sees himself less than the least of all saints; and it ought to be the same with us. The sight of these excellent things lessens us in our own eyes; and this humility will be the consequence of the realization of our privileges. What a glorious testimony that all distinction should be done away! Jew and Gentile-all that belongs to man falls when in the presence of the Counsels of God in Christ. Paul, while contemplating these counsels, saw that he was nothing. The name Gentiles expresses that all was grace. The promise made when the first Adam had sinned, is a promise made to the second Adam; the second Adam will bruise the serpent's head.
The unsearchable riches of Christ are those riches of which we cannot fathom the depth, so immense are they; and the glory which God will give to Christ, according to what He is, and according to the worth of his work, this is the measure of these unsearchable riches. All has been done by Christ and for Christ; all has been created by Him and for Him; and the fact of having presented
Christ to the Gentiles outside the limited revelation of the ancient prophets, brought out the riches of Christ as unsearchable; God can stand in presence of the power of sin, and in Christ, as man, display the power of His grace for the manifestation of his glory.
