What does the Bible say about the heart burning within us?

In Luke 24:32, we see the disciples on the road to Emmaus reflecting on how their hearts burned within them while Jesus talked and opened the Scriptures to them. This burning represents a powerful spiritual awakening and affection stirred by the truth of God's word and the revelation of Christ. It signifies that a true understanding of Jesus and His glory naturally evokes a fervent love and desire to know Him more. This heartburn is a mark of God’s work in us, igniting faith and resulting in worship that transcends mere ritual.
