For I also am a man subject to authority [of a higher rank], with soldiers subject to me; and I say to one, ‘Go!’ and he goes, and to another, ‘Come!’ and he comes, and to my slave, ‘Do this!’ and he does it.”
When Jesus heard this, He was amazed and said to those who were following Him, “I tell you truthfully, I have not found such great faith [as this] with anyone in Israel.
Many believers do not understand the authority and privileges they have in Christ. Such privileges as speaking God's word with faith for situations to respond with immediate effect.
