Let me say from the outset that I believe that Don Piper believes what he is saying & believes he had a real experience, however when comparing his experience with Scripture, his experience is at best a direct contradiction of the Bible.
Don Piper writes “none of the hymns that filled the air were about Jesus' sacrifice or death. I heard no sad songs & instinctively knew that there are no sad songs in heaven. Why would there be?” so Piper is asserting that there are no sad songs in Heaven & so they don't sing about the sacrificial death of Christ. Really? Well the Apostle John actually saw the throne of God, & witnessed the worship in Heaven. Revelation 4-5 the twenty-four elders fell down before the Lamb & sang a new song saying, Worthy are You to take the book and to break its seals; for You were slain, and purchased for God with Your blood men According to Piper they don't sing about the death or sacrifice of Jesus. According to Scripture, Heaven does sing praise to the Lamb who was slain.
One pastor has said, “I believe this is the most pervasive, subtle, unrecognized, & yet destructive error contained in the book. I believe that this book undermines the readers’ confidence in Scripture, encourages distrust of Scripture, & encourages unbelief in God's Word. This book elevates experience - specifically his - above God's written revelation as a source of comfort, assurance, & hope for the believer & repeatedly suggests that Scripture can be believed because of what Piper has experienced.” I agree whole heartedly with this.
2 Corinthians 5:8, We are confident, yes, well pleased rather to be absent from the body and to be present with the Lord. SLJ says that “the preposition “with” here is not the kind of preposition we might normally see or expect. There are prepositions often translated “with” that mean simply “in the company of” or “with” in the many ways in which we use the term in English, but this is a very vivid living term. It means “with” in the sense of “in communion with.” In fact, its basic meaning is facing.”
(Also, the preposition pros + the accusative ton kyrion (with the Lord) suggests not just impassive spatial proximity to Christ but dynamic, interpersonal communion with him). Why is this important? Because Piper says he never saw God or Jesus, he was not facing Jesus, he was not communing with Jesus. Who is correct? Don Piper or Scripture?
You see Piper’s book, his tale, his experience contradict what the Scripture says will take place when we die.
So this book is simply trash, it contradicts the Bible, it diminishes the sufficiency & authority of the Bible, it moves people away from the revealed truth of God from God towards human experience. It elevates human experience to the level of Scripture, even above it as it uses the experience to verify the Word instead of the Word verifying the experience. And again if the Word is used to verify the experience it turns out that at best it is deception.
