In the parable of the sower (Mark 4:1-20), the seed of faith falls on four types of soil: the hardened path, rocky ground, thorny ground, and good soil. Grounded in Prayer: A Small Group Training Guide for Congregational Prayer explores how the Holy Spirit works in your heart and the hearts of others to break up the hardened soil of the path, unseat the rocks of distraction, uproot the thorns and thistles of the world, and plant the seed of faith deeply into good soil.
