How do we know repentance is more than just feeling sorry?

Repentance in the biblical sense is not simply a feeling of sorrow for one's actions; it involves a complete turning away from the old life of sin and embracing a new direction in Christ. As outlined in the sermon, while feeling sorry for one's failures is a part of the process, the essence of repentance is abandoning the old ways that provided comfort and delight, and instead pressing on to a new life in Christ. This is illustrated by the examples of Lot's wife, who looked back to Sodom, and Judas, who felt remorseless regret but did not turn to Jesus for deliverance. Christians are called to forget those things which are behind, nurturing a mindset consistent with their new identity in Christ.
