God gives us authority in the name of Jesus the moment we are born again. Authority is ours when we become a child of God. Every believer has God-given authority. It is by the grace of God. It is not something we earn. God’s power works through our God-given authority.
Authority and power go together. Authority is the channel for the power to flow through. The power of the Holy Spirit works in us and through us, as believers. God is the all-powerful One. His power is the greatest power of all! The Holy Spirit lives in us as born again believers. We have the greatest power living in us! (1 John 4:4.)
