The book of Mark is about how Jesus worked miracles in many different ways. Jesus walked on the sea, He healed a deaf-mute man, He healed a mute spirit boy, etc. Jesus predicted that He would die and be resurrected and He told His dissciples that they will kill the Son of Man and He will resurrect on the third day. So Jesus dies on the cross and resurrects as He predicted. People believed that Jesus was God’s son when He actually worked the miracle, they didn’t believe it until they saw it for themselves.
