Israel was saved in the wilderness through the flowing, life-saving water from the rock. So, we are saved unto eternal life through the substitutionary, stricken, saving rock, our Lord Jesus Christ, the rock of our salvation.
We are not reconciled to a holy and just God by our ethnicity, family, or good works. But, by God’s grace we believe in the divinely-chosen Servant, the soul-pleasing Beloved, the multi-national justice Preacher, the unbroken bruised Reed, the quenchless smoldering Wick, the justice-delivering Victor, our Savior, Jesus Christ the Lord.
And while sickness and disease are the plagues of this world, our greatest need is eternal. A healed body may enjoy this life but apart from faith in Christ the soul will go to hell.
