Don Richardson influenced my life in a similar way that Dr. Ralph Winter impacted me. Don Richardson continues to impact and influence my life through one of his very close disciples, Mr. Bob Sjogren of Unveiling Glory Ministries (see http://www.unveilinglory.com/) I highly recommend Bob's ministry, his Cat and Dog Theology, his Homeschooling and Christian School curriculum. His materials, like Don's, has highly shaped the Perspectives Course program as well. Perspectives on the World Christian Movement (see https://perspectives.org/) is the greatest course I've ever taken, and that includes all courses I've taken at The College of William and Mary as well as Regent University! Read Don Richardson's six books. Purchase from this website: https://www.peacechildlegacy.com/home
Praise God from whom all blessings flow... and let Don Richardson influence your life how God wants to! We are all blessed to be a blessing! Not just to receive the "top line" of the blessing but especially the "bottom line" of the blessing... to be a blessing to all peoples, tribes, tongues... all 17,000+ people groups throughout the earth!
