A true return to God requires a complete transformation that reshapes both a person's outward behavior and their most private inner world. The path to forgiveness is always open, offering hope regardless of the depth or history of a person's wrongdoings. The primary approach among commentators is that abandoning sin involves two distinct layers. First, a person must walk away from their practical wrongs. This means stopping bad habits, improper speech, and harmful physical actions [רד״ק, אבן עזרא, ביאור שטיינזלץ]. However, outward change alone is never enough. A person must also cleanse their hidden, inner world, ensuring that their actions, speech, and thoughts are entirely aligned [רד״ק, אבן עזרא].
Looking closer at human nature, there are different types of wrongdoers. One type is a person who gives in to physical desires and temptations. For this individual, the main task is to abandon their destructive practical habits. Another type is someone whose wrongdoing has become deeply ingrained in their very identity, driven by flawed beliefs or a rejection of faith. For this person, the repair must go much deeper, requiring them to completely uproot their false thoughts and misguided beliefs [מלבי״ם].
The journey back to God happens on different levels, depending on a person's motives and how they relate to the Divine. The highest level is returning out of pure love. When a person recognizes their Creator and returns with a sincere, wholehearted confession, it immediately awakens God's mercy and removes any spiritual accusation against them [מלבי״ם, חומת אנך]. There is also a lower, yet still valid, level of return. This occurs when a person is motivated by the fear of punishment, recognizing God as a strict judge who watches over human behavior [מלבי״ם]. When facing this strict standard of justice, the process of erasing the sin completely might demand a more difficult path of self-denial and fasting [חומת אנך].
Despite these different motivations and levels of return, the ultimate promise is one of endless grace. God extends His forgiveness even to those who have committed many severe wrongs [רד״ק]. Even if a person's return is driven entirely by fear rather than love, God's capacity to forgive remains vast and absolute, offering complete hope to anyone willing to make the journey back [מלבי״ם, חומת אנך, מצודת דוד].
