Our culture constantly tells us to look to our own abilities to find strength and success. Tragically, many churches in our day have taken that advice. In this sermon, David Platt shows us why this self-reliant attitude is contrary to what we see throughout the book of Acts as the gospel spreads across geographic and cultural borders. If the church is to carry out God’s mission, then it must rely on God’s power. Making disciples of all nations requires desperate prayer.
