The amazing thing is that God didn’t even have to open the windows of heaven to feed the starving masses. Perhaps God let a tiny bit of His resources flow when He brought manna and blew in meat during their time in the wilderness.
But in this case, you could say He didn’t have to touch heaven at all, He simply used what was already there.
Things that we think are hard, even impossible, don’t even tax God’s creativity, let alone his ability. In what area will you trust Him today?
