I am so thankful for God’s work through John Piper. His "Ask Pastor John" videos are so helpful. All of us have been asked a version of these questions and have either answered wrongly or have heard others answer wrongly. Especially with this topic of the death of an unsaved loved one. The temptation is to give some glimmer of hope to the family members that a prayer mouthed when the deceased was a child was enough to save an unregenerate life. Or that because someone said the "sinner’s prayer" a half dozen times during their life, they’re now in heaven. This is a hard situation, but not a hard question to answer. God’s Word is clear. Thank God for His Word!
