37. They were pricked in heart. Luke doth now declare the fruit of the sermon, to the end we may know that the power of the Holy Ghost was not only showed forth in the diversity of tongues, but also in their hearts which heard. And he noteth a double fruit; first, that they were touched with the feeling of sorrow; and, secondly, that they were obedient to Peter’s counsel. This is the beginning of repentance, this is the entrance unto godliness, to be sorry for our sins, and to be wounded with the feeling of our miseries. For so long as men are careless, they cannot take such heed unto doctrine as they ought. And for this cause the word of God is compared to a sword, (Hebrews 4:12,) because it doth mortify our flesh, that we may be offered to God for a sacrifice. But there must be added unto this pricking in heart readiness to obey. Cain and Judas were pricked in heart, but despair did keep them back from submitting themselves unto God, (Genesis 4:13; Matthew 27:3.) For the mind being oppressed with horror, can do nothing else but flee from God. And surely when David affirmeth that a contrite spirit and an humble heart is a sacrifice acceptable to God, he speaketh of voluntary pricking; forasmuch as there is fretting and fuming mixed with the prickings of the wicked. Therefore, we must take a good heart to us, and lift up our mind with this hope of salvation, that we may be ready to addict and give over ourselves unto God, and to follow whatsoever he shall command. We see many oftentimes pricked, who, notwithstanding, do fret and murmur, or else forwardly strive and struggle, and so, consequently, go furiously mad. Yea, this is the cause why they go mad, because they feel such prickings against their will. Those men, therefore, are profitably pricked alone who are willingly sorrowful, and do also seek some remedy at God’s hands.
