One can help without even seeing or knowing, let alone touching the person being helped. Anonymous donations are an example. Jesus wants more than that. He "touches" the leper.
Touch always carries both love and respect. Touching means building a spiritual relationship or emotional connection between two people. Touching in the act of helping means saying: "you are my brother, you matter to me."
Jesus' third expression is saying, "I am willing; be clean." This expression is a response to the leper's request. Responding to his request with clear and precise words is a form of sincerity and sincerity. Jesus' action of healing is not just an act of generosity but a form of respect for this person's dignity. Jesus addresses this leper and restores him to the status of a person again, not just a sick person.
Holiness and purity are not always attained in a sterile world, avoiding what is dirty, evil, or unclean. Holiness and purity are achieved through an act of love.
This act of love becomes perfect if it is based on sincerity, sincerity, and in the spirit of appreciating others.
