They had seen Jesus in the carpentry shop, had bought King-sized beds from Him and had his quotation for a new fitted-in kitchen unit ... THEN he announced He was the Messiah. 

He tried to do miracles but Mark says,"He COULD NOT do any miracles because of their unbelief."
Bishop Pride Sibiya
Familiarity kills the miraculous anointing on servants of God...we know him...what new thing can he bring ... we saw him grow ... he is so and so's child ... she once did a shameful thing around here ... she is too young/old ... they are too black ... I know his weaknesses...!
Critics are always never miracle-receivers! Kill familiarity and receive your miracle!

Apostle Pride Sibiya
