No question! They believed in healing or they would not have attempted to cure the boy. Jesus shows that if they had real faith instead of mental believing, they would only need a mustard seed of that kind of faith, and the miracle would happen.
Hakuna swali! Wali amini kwa uponyaji au hawange jaribu kuponya yule kijana. Yesu ana onyesha iwapo wangekuwa na imani ya kweli badili ya imani ya akili, wangehitaji tu imani kama punje ya haradali na muijiza ungetukia.
