'Trustees' in the Bible

So then, let us [who minister] be regarded as servants of Christ and stewards (trustees, administrators) of the mysteries of God [that He chooses to reveal].

but he is under [the authority of] guardians and household administrators or managers until the date set by his father [when he is of legal age].

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].
