What is the meaning of authority? Why do preachers and Bible teachers use that term to defend what they do? We can find several descriptions in the scriptures themselves.
Matthew 8:5-10 shows that the Roman centurion understood what the word meant. Authority was understood to mean the one holding that power has a right to say what should be done and that “law” or direction should be followed absolutely and without deviation. The centurion noted this was what his authority meant, and he understood Jesus had such authority too. When Jesus says, “Go,” we should go, and when he says, “Come,” we should come.
