Goe forth of the Arke] At Gods command he came into the Arke, Gen. Chap. 7. vers. 1. and by his command he is to goe forth againe; in time of danger he shut him up like a prisoner, but it was to preserve him; Gods restraints are mercies not in this case alone; see Isaiah 26:20. and now the danger is past, and libertie safe, he is set free to goe abroad; he continued his confinement untill the Lord inlarged him: It is good to have his warrant for our movings to and fro; our coming in, and going out, and walking in such wayes as we may comfortably expect to have Angels to attend our steps, Psal. 91. vers. 11. And if we take the Arke for a type or figure of the Church, (as Divines use to doe, and may well agree with Saint Peters comparison, 1 Pet. 3. 20. 21.) it may point us to a duty of importance in our Christian practise, viz. that none must be admitted into the Church, or excommunicated out of it, but for causes, and in a manner warrantable by the Word of God.
