from the invasion of open enemies, and that they shall not be exposed as a prey to them, as formerly they had beene. This al∣so in Scripture-language is understood by their being holy, as it is observed in Obad. v. 17. partly because of the ceremonial pollu∣tion that of old did accompany the invasion of their land by hea∣thens, beside that it did obscure their priviledge of being the Lords peculiar, sanctified, and set apart people; But chiefly, be∣cause (as is usual in wars, when prophane Nations invade the Cuhrch) they did overturne holy ordinances, and cast all loose and in confusion. Doct. 1. Interest in God is the great ground of the Churches encouragement; for, it is held out as their great mercie, I am the Lord your God. 2. This interest is yet more sweet when it is evidenced by his presence and the gracious effects thereof among his people, and he is not provoked to forsake them, though they be his; Therefore it is added, I am the Lord your God dwelling in Zion. 3. It is an addition to all these mer∣cies, when not only matters stand so, but the Church knoweth it, and is convinced of it; And this must be Gods own work, with∣out whose help, they will neither see interest nor presence, who yet in reality enjoy both; Therefore he undertakes it, to make their comfort and mercy compleat, Ye shall know that I am the Lord your God, &c. See 1 Cor. 2.12. 4. The Lord will in due time make his interest in, and presence with his people con∣vincingly clear, by visible dispensations and actings for them; for, so (by what I will do for you) shall ye know that I am the Lord your God, &c. 5.

Gods presence with a people must be entertained and proven by their holinesse; for, then it is my holy mountaine, and Jerusalem is holy. See Psal. 93.5. 7. It is God only who can undertake for making his people holy, and it is their duty to deny themselves, and imploy him for that end; for, it is his pro∣mise, then shall Jerusalem be holy. 8. Where a people have re∣al sanctification, as a fruit and evidence of Gods presence, they have also the promise that he will preserve them from the invasion of enemies; for, then shall Jerusalem be holy in this respect also, that no stranger shall passe thorow her, to wit, in an hostile way. And albeit this seeme to be a peculiar promise to convert∣ed Israel, and albeit others (even Judah it self) when they have been upon the amending hand, have met with sad stormes from enemies; Yet certainly such have the promise of this mercy, when
