Ezekiel takes up a lamentation for the children of Israel, even before they were taken into captivity. They had been given all they needed to serve God, like strong a vine with ready access to water. Despite great men of faith like Moses and David, Israel eventually rejected God and so they would be shortly removed from the perfect vineyard to the wilderness.
A similar idea is expressed by Jesus in Luke 16, “no servant can serve two masters…you cannot serve God and money.” We’ve been called to serve God with our whole existence, to be “like a tree planted by streams of water that yields its fruit in its season”. Let’s seek the true riches God has offered, to be like the vine planted by water, freely soaking up the water of life available in God’s word.
