In this lesson, A Killer Comes to Christ, only God can heal the wounds that He makes. God uses trials to mark our lives with the marks of commitment. When these wounds began to mark our lives, we cannot afford to allow them. Never, never, never, for a moment think, that your darkest trial, your most difficult task, the most hurtful situation in your life, is without purpose. There is indeed purpose in the pain that God allows men to walk through.
