The Jewish leaders questioned the authority of Jesus and asked Him for a sign that God had given Him the authority to cleanse the temple. Jesus agreed to their demand, but with an answer that completely baffled them. No one could build this temple in three days, it would take years. They eventually saw the sign that Jesus was referring to, but the leaders probably didn’t know it because of their unbelief. Human nature hasn’t changed, people are still looking for a sign. How often do we miss what God is doing because of our “little faith”? Jesus knows whether we really believe or not when we ask Him for something. We know the “temple” that Jesus was speaking about was rebuilt (resurrected) in 3 days. Is the Cross and the Resurrection enough for us or do we still need a sign?
37 Don’t believe me unless I carry out my Father’s work. 38 But if I do his work, believe in the evidence of the miraculous works I have done, even if you don’t believe me. Then you will know and understand that the Father is in me, and I am in the Father.”–John 10:37,38 (NLT)
When Jesus completed the work His Father had sent Him to do, He said “It is finished”.
