'Powers' in the Bible

who has gone into heaven and is at the right hand of God [that is, the place of honor and authority], with [all] angels and authorities and powers made subservient to Him.

Just as each one of you has received a special gift [a spiritual talent, an ability graciously given by God], employ it in serving one another as [is appropriate for] good stewards of God’s multi-faceted grace [faithfully using the diverse, varied gifts and abilities granted to Christians by God’s unmerited favor].
