What astonishes God?People abandoning His fountain and digging their own water tanks (Jer. 2:12-13). God calls heaven and earth to shudder with astonishment at four contrasts: 1. Fountain drinking v Tank digging Drinkers come with buckets to fill. Diggers come with shovels to dig. Drinkers are refreshed. Diggers are exhausted. 2. One fountain v Many tanks We only need one fountain. There are never enough tanks. 3. Full fountain v Leaky tanks The fountain is always running. The tanks are always running out. 4. Pure fountain v Poisonous tanks The fountain is life-giving, but the stagnant muddy tank-waters are full of hidden death. You carrying a bucket or a shovel? You a drinker or a digger?
