Be reconciled: the journey is not based on our own strength. No one can be reconciled to God on his or her own. Heartfelt conversion, with the deeds and practices that express it, is possible only if it begins with the primacy of God's work.
What enables us to return to him is not our own ability or merit, but his offer of grace. Grace saves us; salvation is pure grace, pure gratuitousness. Jesus says this clearly in the Gospel: what makes us just is not the righteousness we show before others, but our sincere relationship with the Father.
The beginning of the return to God is the recognition of our need for him and his mercy, our need for his grace. This is the right path, the path of humility. Do I feel in need, or do I feel self-sufficient?
