Welcome to the Gospel Coalition podcast, equipping the next generation of believers,

pastors, and church leaders to shape life and ministry around the gospel.

Without further ado, let me read from 1 Corinthians 9.

1 Corinthians 9 verses 19 to 23.

Then I'll pray and then we'll plunge in.

1 Corinthians 9, 19 to 23.

Okay. 19 to 23. Though I am free and belong to no one, I have made myself a slave to everyone to win as many as possible.

To the Jews, I became a Jew, to win the Jews. To those under the law,

I became like one under the law, though I am myself not under the law, so as to win those under

the law. 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, though I am not free from God's law, but am under Christ's law, so as to win

those not having the law. 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.

I do all this for the sake of the gospel that I may share in its blessings.

This is the word of the Lord.

Let us pray.

And now may the words of my mouth and the meditation of all our hearts be acceptable in your sight.

O Lord, our strength and our Redeemer.

In Jesus' name, amen.

The name was, in fact, a pseudonym.
