set your mind at rest

I urge you earnestly not to spend time thinking about the past. If your time was well-used, then let us give God glory. If it was wasted, let us despise it and trust in the goodness of the heavenly Father. Therefore I exhort you to set your mind at rest with a consoling thought that any part of your life that was not well spent has already been forgiven by our most tender God. – Padre Pio
