In “Addition by Subtraction,” Josiah DeRoos (Summit Faculty) challenges us to see that true spiritual growth often begins when God removes rather than adds. Drawing from Scripture and real-life examples, he explores how disorientation, doubt, and loss can become divine invitations to deeper revelation. Like Peter, who was transformed through failure, we are called to allow God to subtract old ways of thinking so that new truth and freedom can take root. Recorded live at Summit International School of Ministry, this message reminds us that every subtraction in Christ leads to addition in Him — renewal, revelation, and restored faith.
