Philippians 1:28; Philippians 2:3; Philippians 4:6

28 And in nothing terrified by your adversaries : which is to them an evident token of perdition, but to you of salvation, and that of God.
3 Let nothing be done through strife or vainglory; but in lowliness of mind let each esteem other better than themselves.
6 Be careful for nothing; but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God.
