Romans 15:16
in appointing me to be a minister of Christ Jesus to the Gentiles. I am serving like a priest in preaching God's good news, so that the Gentiles might be like an acceptable sacrifice [to God], dedicated by the Holy Spirit.
Romans 12:1-2
So, I urge you, brothers, because God is so merciful [to us], to offer your bodies as a living sacrifice, [fully] dedicated and very pleasing to God. For this is a reasonable [or spiritual] way for you to worship [or serve] Him.
Philippians 2:17
But even if I am poured out like a drink offering [See Ex. 29:38-41] on the sacrifice and service produced by your faith, I am glad and will rejoice with all of you. [Note: Paul here likens the possible pouring out of his blood to the wine and oil of the Old Testament sacrifice, which is then likened to the Philippians' faithful service to God].
1 Peter 2:5
And you yourselves are also like living stones, being constructed into a spiritual house. For you are like holy priests who offer spiritual sacrifices that are acceptable to God through Jesus Christ.
