{f} If she is a wall, we will build upon her a palace of silver: and if she is a door, we will inclose her with boards of cedar.

(f) If she is sure and fast, she is fit for her husband to dwell in.

Wesley's Notes

8:9 If - This seems to be Christ's answer to the foregoing question of the Jewish church. Christ engages himself to provide for her, as suits best with her condition. If the Gentiles when they are converted shall be like a wall, strong and firm in faith; We, my Father, and I, and the Holy Ghost, as the principal builders, and my ministers as workers with, and under us, will build upon her a palace of silver, will add more strength and beauty to her, will enlarge and adorn her; and if she be as a door, which is weaker than a wall; if she be weak in faith, yet we will not therefore reject her, but we will inclose or (as many others render the word) strengthen or fortify her with boards of cedar, which are not only beautiful, but also strong and durable.

Jamieson-Fausset-Brown Bible Commentary

9. wall . door-the very terms employed as to the Gentile question (Ac 14:27; Eph 2:14). If she be a wall in Zion, founded on Jesus Christ (1Co 3:11), we will not "withstand God" (Ac 11:17; 15:8-11). But if so, we must not "build" (Ac 15:14-17) on her "wood, hay, stubble" (1Co 3:12), that is, Jewish rites, &c., but "a palace of silver," that is, all the highest privileges of church communion (Ga 2:11-18; Eph 2:11-22). Image from the splendid turrets "built" on the "walls" of Jerusalem, and flanking the "door," or gateway. The Gentile Church is the "door," the type of catholic accessibleness (1Co 16:9); but it must be not a mere thoroughfare but furnished with a wooden framework, so as not merely to admit, but also to safely enclose: cedar is fragrant, beautiful, and enduring.

Matthew Henry's Concise Commentary

8:8-12 The church pleads for the Gentiles, who then had not the word of God, nor the means of grace. Those who are brought to Christ themselves, should contrive what they may do to help others to him. Babes in Christ are always seen among Christians, and the welfare of their weak brethren is an object of continual prayer with the stronger believers. If the beginning of this work were likened to a wall built upon Him the precious Foundation and Corner-stone, then the Gentile church would become as a palace for the great King, built of solid silver. If the first preaching of the gospel were as the making a door through the wall of partition, that door should be lasting, as cased with boards of durable cedar. She shall be carefully and effectually protected, enclosed so as to receive no damage. The church is full of care for those yet uncalled. Christ says, I will do all that is necessary to be done for them. See with what satisfaction we should look back upon the times and seasons, when we were in his eyes as those that find favour. Our hearts are our vineyards, which we must keep with all diligence. To Christ, and to his praise, all our fruits must be dedicated. All that work for Christ, work for themselves, and shall be unspeakable gainers by it.
