As we listen to the first reading from the Acts, we wonder how those Gentiles opened their hearts to the gospel of Christ. But the Acts does not give much explanation except saying, “The Lord opened” their hearts.

Probably that is the most precise explanation. It was not the Gentiles who opened their hearts. It was not their work or to their credit to recognize and accept the divine voice and message. It was the Holy Spirit who exposed them to a favourable disposition to welcome the apostles. And it was also the Holy Spirit who made their souls and spirits desire for the truth and wisdom of the Lord. And it was also the Holy Spirit who opened their ears to the voice of Christ.

I have never met a Christian all whose family or friends faithfully practice the faith. All of us have more than one family members or friend who does not go to church anymore. I am no exception here. All of us have tried to encourage them to go back to church. And all of us pray for them. But our efforts and prayers often seem futile and useless.

Were the apostles discouraged and disappointed at ridicules, hostility, or ignorance from their audience? Although the apostles brought many Gentiles and Jews to the Lord, I am sure more people rejected the gospel. The apostles knew that it was their responsibility to preach the gospel. But they also knew that it was the Holy Spirit, the Lord, who prepared and opened people’s hearts. It is why they could keep preaching without despair and frustration.

We do not know how the Lord opens people’s hearts. Ask ourselves. How did he open my heart? Even I have a hard time explaining. Sometimes it remains a mystery. However, when we trust the Lord and keep praying and proclaiming the gospel, we will see the wondrous fruit of the Holy Spirit among people.
