Luke 24:32 They said to each other, “Did not our hearts burn within us while he talked to us on the road, while he opened to us the Scriptures?”
The Word of God has an effect on all who experience it. As Jesus walked with the disciples that were headed to Emmaus, He opened up the Scriptures to them in a very real way, showing them the overall theme of the Bible – Himself. As they heard all of this, presumably for the first time (though they “knew” the Scriptures), their hearts burned within them. After inviting Jesus to stay with them their eyes were opened and they saw clearly who He was and that God had revealed Himself, through Jesus and through the Scriptures.
And what happened immediately after that? The result was exactly what it was for anyone whose heart burns from within – they had to go share what they now knew. When your heart is burning, you can’t help but tell the world what made it so. After hearing Jesus’ words, experiencing Him, and having their eyes opened to the truth, they immediately went out and spread the news that the Christ had risen. There was no doubt left in their minds that it was true and that everyone needed to know. They knew the value of this news. They knew what it meant to all mankind.
Experiencing Jesus does this to a person. He has such an impact on us that our hearts burn from within and we can’t help but share the Gospel with all of those around us. No one has ever had such an effect on all the world. Those who experienced Him for who He is turned the world upside down (Acts 17:6) and we can continue to do so for His glory.
