First to those in Damascus, then to those in Jerusalem and in all Judea, and then to the Gentiles, I preached that they should repent and turn to God and demonstrate their repentance by their deeds.Acts 26:20 NIV
In Paul’s defense before Agrippa and Festus he shared the content of the message he had proclaimed to everyone he encountered. And it was a two-part message. The first part was to repent and turn to God. This is what we would commonly identify as conversion which includes repentance and faith (turning to God). The second part of the message concerned life after conversion. Demonstrating that their conversion was real by the way they lived.
Is it possible to truly repent and turn to God without it affecting the way you live your life? Repentance and turning to God are a major course correction in one’s life. And one that should be obvious for all to see. Demonstrating your repentance by your deeds.
