The Lord appoints us and gives instructions how to fullfil the missionary tasks. As our Master he chooses us to be like him. He teaches to love one another and to preach the Gospel around the world. He takes care of everyone in every place and in every time.
The Lord speaks to the heart of his disciples and encourages them to start working for the salvation of humankind. Firstly, he tells them that they should pray and ask God for his blessing. Secondly, he suggests them to be humble towards others. He explains that people are hurt and fragile. For that reason, they need medicians who will cure them. They don't need more things but gentleness, love and patience.
Moreover, Jesus Christ focuses on the families who are in need of peace. He wants his apostles to be peaceful persons. Thus, they will be able to share their inward peace with the needy. People are lonely and the disciple of Christ should be with them in their experiences.
All the people look for support and guidance. Therefore, the apostles are those who cure the sick with the words of peace and love. Thus, the Kingdom of God becomes present in the world.
