What does 'the wells of salvation' mean in Isaiah 12?

The phrase 'wells of salvation' in Isaiah 12:3 symbolizes the richness and depth of spiritual sustenance available in Christ. Just as physical water is necessary for life, Christ as the 'well of water springing up into everlasting life' (John 4:14) is essential for our spiritual existence. He provides refreshment and nourishment to our souls, meeting every need and quenching the spiritual thirst that every person has. This imagery assures believers of the never-ending supply of grace and mercy available to them.
