what does the bible say?
In the devotional book Jesus Calling, the author, Sarah Young, shares what she says are messages she received from Jesus. This claim counters the Christian understanding that the Bible is a closed revelation, meaning that God's word is complete. Though Young claims the messages are from Christ, she hedges by saying her words are not on par with the Bible. But her underlying claim about messages from God can cause some readers of Jesus Calling to equate the author's words with divine revelation.
Claiming to have received further messages from God is akin to alleging new revelation, which implies content on a par with the Bible. In Scripture, God expresses a harsh warning for people who falsely claim to speak for Him (Deuteronomy 18:20). Scripture also warns about adding to or detracting from God's revelation (Deuteronomy 4:2, 12:32; Revelation 22:18-19). Though those passages pertain to limited content within the Bible, the principle remains: Claiming revelation from God carries serious implications.
Only God can read hearts (1 Samuel 16:7), so Christians cannot fully know someone's intentions. But the Bible testifies to itself as the source for life guidance and indicates that we should test every claim against what Scripture says (2 Timothy 3:16-17; 1 John 4:1). This implies that believers must approach books like Jesus Calling with a great deal of skepticism.
