Colossians 2: 9 For the entire fullness of God’s nature[b] dwells bodily[c] in Christ, 10 and you have been filled by Him, who is the head over every ruler and authority. (HCSB)
Above verses reveal the true potential of a believer. V:9 says who is Jesus and verse 10 says you are filled with that Jesus in your body.
You have the authority and power with you which was given by Jesus. That power is supreme to any other power, ruler or authority in this world. So you should use that power and authority to command the devil and disease to leave. Using that power you may lead a successful Christian life.
