Evil thoughts destroy the soul. The converting power of God changes the heart, refining and purifying the thoughts. Unless a determined effort is made to keep the thoughts centered on Christ, grace cannot reveal itself in the life. The mind must engage in the spiritual warfare. Every thought must be brought into captivity to the obedience of Christ. All the habits must be brought under God’s control.— Letter 123, 1904 (1MCP 69.2) MC VC
