Why is it essential for Christians to repent and turn to God?

Repentance and turning to God are not optional aspects of the Christian faith; they are commands given by Christ as highlighted in Paul's preaching (Acts 26:20). Repentance involves recognizing our sinful nature and the need for divine assistance to turn away from darkness and towards the light of Christ. This is crucial as it leads to a true transformation of life exemplified through 'works meet for repentance,' which reflects the genuine change that occurs in a believer's life. The call to repentance emphasizes God's mercy in offering forgiveness and establishing a relationship with Him, making it vital for every Christian's walk of faith.
