I find it hard to believe that there is any Christian left that has not in some manner been blessed and challenged by the tremendous wealth of free resources made available at Desiring God. They have literally opened the doors of their vaults and made just about every single sermon, essay, book, and audio available for free download.
Matt Perman of Desiring God wrote an essay challenging all other ministries to do the same. I say right on!
1 Corinthians 9:12b
But we did not use this right. On the contrary, we put up with anything rather than hinder the gospel of Christ. 13Don’t you know that those who work in the temple get their food from the temple, and those who serve at the altar share in what is offered on the altar? 14In the same way, the Lord has commanded that those who preach the gospel should receive their living from the gospel.
15But I have not used any of these rights. And I am not writing this in the hope that you will do such things for me. I would rather die than have anyone deprive me of this boast. 16Yet when I preach the gospel, I cannot boast, for I am compelled to preach. Woe to me if I do not preach the gospel! 17If I preach voluntarily, I have a reward; if not voluntarily, I am simply discharging the trust committed to me. 18What then is my reward? Just this: that in preaching the gospel I may offer it free of charge, and so not make use of my rights in preaching it.
19Though I am free and belong to no man, I make myself a slave to everyone, to win as many as possible. 20To 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. 21To 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. 22To the weak I became weak, to win the weak. I have become all things to all men so that by all possible means I might save some. 23I do all this for the sake of the gospel, that I may share in its blessings.
