Two water images are used in these verses to show us something good and something bad. As cool, pure water refreshes a thirsty person, so good news coming from a distant land revives sagging low spirits. This is true especially when we have a vital interest in such a distant land, and we form anxious speculations over it because we are far away from it, until our doubts are erased by objective reports. How reviving good news is from the courts of heaven that tells us that in Christ we have peace with God (Romans 5:1–2)!
25 Like cold water to a thirsty soul, so is good news from a far country.
