"Isa. 55:1, Ho, everyone that thirsts, come to the waters, and he that has no silver, come buy, and eat
As if the Lord were grieved, and said, 'Woe is me, Alas that thirsty souls should die in their thirst, and will not come to the water of life, Christ, and drink gratis, freely, and live.' For the interjection, 'Ho,' is a mark of sorrowing, as ah, or woe, everyone that thirsts. It expresses two things, 1. A vehemency and a serious and unfeigned ardency of desire that we do what is our duty, and the concatenation of these two, extremely desired of God: our coming to Christ and our salvation. This moral connection between faith and salvation is desired of God with his will of approbation, complacency, and moral liking, without all dissimulation, most unfeignedly; and whereas Arminians say, we make counterfeit, feigned, and hypocritical desires in God, they calumniate and cavil egregiously, as their custom is."
