Once again: If it's been a long time since you last confessed, go now! Make it a regular part of your spiritual life and formation. God's outpouring of grace and mercy is abundant, but it is not forced on us. Too many people today do not believe in sin or do not think they are capable of committing sin. Yet, none of us is without sin! Why refuse God's free offer of forgiveness and reconciliation? Go!
