When we are under the authority of Christ, we have all His authority behind us. The usage of the word for authority (exousia ) is instructive and inspiring.

1. Authority to Heal “Power (exousia) to heal sicknesses” (Mar_3:15).

2. Authority over Demons. “Power (exousia) over unclean spirits” (Mar_6:7).

3. Authority to Preach. “Go... all power (exousia) is given unto Me” (Mat_28:18).

4. Authority to Become. “Power (exousia) to become the children of God” (Joh_1:12).
