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
In Paul’s defense before Agrippa and Festus he shares the content of the message he has proclaimed to everyone he encounters; and it is a two-part message. The first is 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 concerns 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 that should be obvious for all to see. Demonstrate your conversion by your deeds.
