(2.) To what privileges they shall be welcome, v. 7. Three things are here promised them, in their coming to God:—[1.] Assistance: "I will bring them to my holy mountain, not only bid them welcome when they come, but incline them to come, will show them the way, and lead them in it." David himself prays that God by his light and truth would bring them to his holy hill, Ps. xliii. 3. And the sons of the stranger shall be under the same guidance. The church is God's holy hill, on which he hath set his King, and, in bringing them to Zion Hill, he brings them to be subjects to Zion's King, as well as worshippers in Zion's holy temple. [2.] Acceptance: "Their burnt-offerings and their sacrifices shall be accepted on my altar, and be never the less acceptable for being theirs, though they are sons of the stranger." The prayers and praises (those spiritual sacrifices) of devout Gentiles shall be as pleasing to God as those of the pious Jews, and no difference shall be made between them; for, though they are Gentiles by birth, yet through grace they shall be looked upon as the believing seed of faithful Abraham and the praying seed of wrestling Jacob, for in Christ Jesus there is neither Greek nor Jew, circumcision nor uncircumcision. [3.] Comfort. They shall not only be accepted, but they themselves shall have the pleasure of it: I will make them joyful in my house of prayer. They shall have grace, not only to serve God, but to serve him cheerfully and with gladness, and that shall make the service the more acceptable to him; for, when we sing in the ways of the Lord, then great is the glory of our God. They shall go away and eat their bread with joy, because God now accepts their works, Eccl. ix. 7. Nay, though they came mourning to the house of prayer, they shall go away rejoicing, for they shall there find such ease, by casting their cares and burdens upon God, and referring themselves to him, that, like Hannah, they shall go away and their countenance shall be no more sad. Many a sorrowful spirit has been made joyful in the house of prayer.
