John Wesley on Philippians 2:17

Here he begins to treat of the latter clause of Php 1:22. Yea, and if I be offered - Literally, If I be poured out. Upon the sacrifice of your faith - The Philippians, as the other converted heathens, were a sacrifice to God through St. Paul's ministry, Rom 15:16. And as in sacrificing, wine was poured at the foot of the altar, so he was willing that his blood should be poured out. The expression well agrees with that kind of martyrdom by which he was afterwards offered up to God.
