OSL

OPERATION: SOLID LIVES

It was in 2003 that the Lord impressed Jerry Dirmann, Senior Pastor of The Rock, to disciple his congregation using a modified version of a youth discipleship program he had written years earlier. Jerry called this version, “OPERATION: SOLID LIVES” (OSL). While OSL started out slowly, by 2004 it had exploded. By 2008, OSL began to spread to other churches throughout the United States and Internationally. Now OSL is being used by hundreds of churches, resulting in thousands of lives being radically transformed.
