The end of the age brings with it two opposing prospects for every person - mercy or judgment. We need not only to choose mercy, but to invest our lives in sharing God's gracious offer of mercy to those whose prospect is judgment. In this booklet, Derek Prince shows us from Scripture that God has given us a wonderful gift in the Holy Spirit. He comes like the rain to empower us to bring forth a bountiful harvest. Learn how to be used by God to increase the harvest of mercy and establish Christ's Kingdom on the earth.
