19 Though I am free and belong to no one, I have made myself a slave to everyone, to win as many as possible. 20 To the Jews I became like a Jew, to win the Jews.To those under the law I became like one under the law (though I myself am not under the law), so as to win those under the law. 21 To those not having the law I became like one not having the law (though I am not free from God’s law but am under Christ’s law), so as to win those not having the law. 22 To the weak I became weak, to win the weak. I have become all things to all people so that by all possible means I might save some. 23 I do all this for the sake of the gospel, that I may share in its blessings.
Paul had a fine example of how to become all things to all people so that by all possible means he might save some. Of course his example is our example — the person of Jesus Christ.
Jesus’ first transformation was in becoming an infant and growing up into a full-fledged human male, becoming like us, in other words. A slightly later transformation was in becoming a well-educated religious scholar ready to debate and educate His elders in the temple. Yes, Jesus became a Bible Scholar! A later transformation was in becoming like a sinner by joining in the revelry of sinners inside the home of a tax collector — no, He did not sin, but He was not afraid or leery of being seen with sinners. Yes, Jesus became a partygoer!
Paul took Jesus’ example to heart. Paul deliberately did not disassociate himself from others. He did not shun people because they were not Christian, or because they did not fully understand their freedom under Christ, or that they were Jews in lock step with the law, or that they persecuted him for being different from them. Rather he associated himself with all types of people and made himself similar to them in order to gain their respect, their trust, perhaps even their friendship and so save some of them.
We ought to do the same.
