[As] cold waters to a thirsty soul,.... Water is naturally cold; and is by classic writers expressed by "cold" itself , and is very refreshing to one athirst through heat: or, "to a weary soul" ; to one wearied with labour; or to a traveller weary with travelling, especially in hot countries, as in the deserts of Arabia, or in places where it is rare to meet with a brook, stream, or fountain of water; which, when he does, it is exceeding pleasant and agreeable to him;so [is] good news from a far country; so acceptable is it to hear from a friend in a distant part of the world, and particularly to hear good news of him.
Such is the Gospel; it is good news, and glad tidings of good things; it brings the good news of the grace, and favour, and good will of God to men; of his appointment and provision of a Saviour for them; of the incarnation of Christ; of salvation being wrought out by him for the chief of sinners, which is free, full, and for ever; and of peace, pardon, righteousness, and eternal life, through him, And this comes "from a far country"; from heaven, the better country than Canaan, which was a type of it, or any country in this world, and which is afar from hence; the Gospel comes from God in heaven, and it is a report concerning that; it is good news to saints, of an estate they have there, an inheritance, a house, a city and kingdom prepared for them there: this news is brought by the prophets of the Old Testament, who diligently inquired of salvation by Christ; by the angels at Christ's incarnation; by John the Baptist, the forerunner of Christ; by Christ himself, who was anointed to preach good tidings to the meek; and by his apostles, and all the faithful ministers of the word: and the message they bring is good news; not to carnal and self-righteous persons, but to sensible sinners; and to them it is as cold waters to a weary or thirsty soul; it assuages the heat of the law, and the wrath that works in the conscience; it quenches the thirst of carnal things, and after a man's own righteousness; it revives and refreshes his weary drooping spirits, and fills him with a joy unspeakable and full of glory; as Jacob's spirits were revived on hearing the good news of Joseph, Ge 45:26.
