John Gill Commentary Matthew 7:8

"for every one that asketh receiveth; and he that seeketh findeth; and to him that knocketh it shall be opened." — Matthew 7:8 (ASV)

For everyone that asketh receiveth For God is no respecter of persons; whoever makes application, whether he is a Jew or a Gentile, rich or poor, bond or free, a man of great gifts or humble abilities, provided he asks aright, from right principles, and with right views, shall not labor in vain; but shall receive all such good things at the hand of God, as are suitable and convenient for him.

And he that seeketh findeth; he that seeks for God in Christ, the grace and mercy of God, the kingdom of God, and his righteousness; that seeks after the true riches, both of grace and glory, shall be sure to find them; see (Proverbs 21:21).

And to him that knocketh it shall be opened: that is, to him that is constant at the throne of grace, who continues knocking at the door of mercy, and will not be denied, it shall be opened to him; and he shall have entrance into the holiest of all by the blood of Jesus.
