This is all about the inland waters. What’s special about the inland rivers and fountains, the springs that source so many watercourses? They are places of beauty and tranquillity.
Imagine people are living comfortable rich lives in a beautiful picture postcard village, and everything is peaceful, and nothing ever goes wrong in the village. And then there is an inland flood, and their lives are turned upside down, and filthy water comes right up into the ground floor. You can’t escape catastrophes, and, says Revelation 8, they are not natural. They are in the plan of God, part of his sovereign purpose, to humble us, shake us, warn us. Of course Christians undergo them too, but Christians are different. You see the worldling: all his hopes are in that picture postcard cottage. All his treasure, all the things he loves, are tied up with that idyllic place, everything that counts for him and his future. But it’s shattered and he stares into the television camera and he says with tears, ‘I’ve lost everything.’ But the Christian: though of course he feels the difficulty and the loss and the sadness, he has a hold upon the Lord, and goes to prayer, and has hopes far higher than the pretty home and the things that for the moment have been marred, and seized away, and looks to heavenly things and the blessing of God and the walk of holiness. So yes, these things come upon the just and the unjust, but it’s much, much worse for the unjust, because they have no spiritual view, no heavenly hope no comfort from on high, no provision from God.
