It is when we reflect on the truth that our heart catches fire. Think of the Emmaus disciples on the afternoon of Easter Day. The risen Lord joined them on their walk and explained to them out of the Scriptures how the Messiah had to suffer before entering his glory. Later, after he had left them, they said to each other: ‘Were not our hearts burning within us while he talked with us on the road and opened the Scriptures to us?’ (Lk. 24:32). This inner burning of the heart is a profound emotional experience, but it was Jesus’ biblical teaching which prompted it. Nothing sets the heart ablaze like fresh vistas of truth.
