The Essentials to Defend the Faith of the Gospel
Philippians 1:27-30 (New King James Version)
27 Only let your conduct be worthy of the gospel of Christ, so that whether I come and see you or am absent, I may hear of your affairs, that you stand fast in one spirit, with one mind striving together for the faith of the gospel,
28 and not in any way terrified by your adversaries, which is to them a proof of perdition, but to you of salvation, and that from God.
29 For to you it has been granted on behalf of Christ, not only to believe in Him, but also to suffer for His sake,
30 having the same conflict which you saw in me and now hear is in me.
