Everything the believer does — if only he does it as in God’s presence and as a service to God — it is a priestly service, well-pleasing to God. ‘Whether therefore ye eat, or drink, or whatsoever ye do, do all to the glory of God’ (1 Corinthians 10.31). ‘Whatsoever ye do in word or deed, do all in the name of the Lord Jesus, giving thanks to God and the Father by Him.’ (Colossians 3.17). In this way, all our actions become thank-offerings to God.
