 Verse 30, so they ask him, well, what miraculous sign will you give us that we may see it and believe in you, as though feeding 5,000 yesterday wasn't a very good one? But aren't we that way? I could give you people's names who God supernaturally healed their kids in ICU, and they promised they'd walk with Jesus forever and ever and ever, and they're so far from God. We so quickly forget God's miracles. God's acts will never sustain you, only his ways.
