New Defender's Study Bible Notes
24:32 our heart burn. “Christian heartburn” results when the Lord—through the indwelling Spirit—opens the Scriptures today as we read and obey God’s Word. “His word was in mine heart as a burning fire shut up in my bones, and I was weary with forbearing, and I could not stay” (Jeremiah 20:9).
24:32 opened to us. Note the order of this passage. When the Scriptures were opened, first their eyes were opened (Luke 24:31) and then their understanding was opened (Luke 24:45).
