27 Only conduct yourselves in a manner worthy of the gospel of Christ, so that whether I come and see you or remain absent, I will hear of you that you are standing firm in one spirit, with one mind striving together for the faith of the gospel; 28 in no way alarmed by your opponents—which is a sign of destruction for them, but of salvation for you, and that too, from God. 29 For to you it has been granted for Christ’s sake, not only to believe in Him, but also to suffer for His sake, 30 experiencing the same conflict which you saw in me, and now hear to be in me. (Philippians 1:27-30 NASB)
Notice in the passage above that Paul’s call for believers to stand firm together in one spirit, with one mind striving together for the faith of the gospel. Notice that those who do this are to do so with no fear of anything that opponents of God’s truth try to do or say against them and the message of the Gospel, that is, the real Gospel, not the Laodicean gospel or social gospel. In any case let us look at the Greek word the NASB translates as “striving” in v27 above, which is συναθλουντες a present, active, participle version of συναθλέω or sunathleō, which is a compound word made up of ἀθλέω or athleō from which we get our English word athlete and athletics and means to strive or contend, to be a champion in the public games, such as wrestling, boxing, et cetera. This word pictures a completely dedicated, single-minded striving that would equal that of committed athlete.
