This is the fourth of four training manuals used by "In Christ's Image Training" (ITIC) online training courses. The vision of ICIT is to train and release hundreds of thousands of Christlike pastors, leaders and intercessors to stand before God on behalf of the world around them. It is strongly recommended that these manuals are read in sequence. The truths in the first manual, "Christlikeness," reveal that our heavenly Father's goal for us is conformity to Christ. The second manual, "Humility," reveals what areas of the heart needs to change en route to Christlikeness. "Prayer," the third manual, provides truths that help empower transformation, not only to ourselves, but to the world around us. This last manual on unity is in many ways the consequence of the previous three. Before God's Spirit moves in world-changing power upon the earth, He first unifies His people. The Bible reveals that every significant move of God was preceded by a unifying work of grace. Indeed, the book of Acts begins with Jesus' disciples praying together "with one mind" (Acts 1:14). The profound truth of God is that Pentecost did not produce unity among the disciples; their unity was the precursor to Pentecost. Our previous three manuals focused on truths that represent foundational realities upon which true spiritual unity is built. In this manual we will see why God hates our divisions and why the unifying of His disciples was the passion of Jesus' final prayers.
