Saturday- the Jewish Sabbath
Mark 9:23 ESV
“And Jesus said to him, “‘If you can’! All things are possible for one who believes.”

On Saturday, the disciples were hiding for fear of the Jewish Counsel and the guards. They were known followers of Jesus and the association with Jesus would bring down judgment on them as well. Frightened, scared out of their minds, no leader to stand up for them, No assurance of what would happen now, they hid themselves. If they would have remembered what Jesus said; “Destroy this temple, and in three days I will raise it up.” If they would have only believed.
Sunday (the 3rd day) was on the way!
