How do we know repentance is necessary for salvation?

The necessity of repentance in salvation is affirmed throughout Scripture, demonstrating that true repentance encapsulates a turning away from sin and a turning toward God. Acts 3:19 states, 'Repent therefore, and turn back, that your sins may be blotted out.' This recognition of sin and the need for change is foundational to a genuine relationship with Christ. Furthermore, we understand that while repentance is crucial, it is the grace of God that enables us to repent and ultimately find salvation in Him, rather than our own efforts or feelings of remorse.
