Jesus really lets the disiples have it! He basically calls them thick! Have you ever doubted, or questioned? It isnt always easy for us to keep or faith, Especially in times of trouble when it looks like evil is winning.
If Jesus kingdom had begun why do we see such terrilble things still going on? The battle has been won but the war still rages, evil doesnt believe it has already lost, so the more we gain ground the more evil fights back. When we doubt it is reassuring to remember that even those closest to Jesus doubted and questioned so it is not something we should lose sleep over , but we should remind ourselves that Jesus is king!
