'Service of God' in the Bible

but now that you are set free from sin, now that you have passed into the service of God, your gain is consecration, and the end of that is life eternal.

who are Israelites; whose is the adoption, and the glory, and the covenants, and the giving of the law, and the service of God , and the promises;

as a priest of Christ Jesus to the Gentiles in the service of God's gospel. My aim is to make the Gentiles an acceptable offering, consecrated by the holy Spirit.
