"because of your partnership in the gospel from the first day until now" Philippians 1:5

Spreading the gospel and participating in the ministries of God is a partnership. It's not an individual task, nor is it limited to within a church or city. Our partnership in the gospel begins from the first day we receive Jesus. This isn't something we do when we feel like it, it is for the rest of our lives.

Persevere for the gospel,
this includes partnering with people we don't know.
