He loves each one of us more than all the mothers in the world can love their children--helping us, inspiring us, blessing... and forgiving. How often we have misbehaved and then cleared the frowns from our parents' brows, telling them: I won't do it any more!--That same day, perhaps, we fall again...-And our father, with feigned harshness in his voice and serious face, reprimands us, while in his heart he is moved, realizing our weakness and thinking: poor child, how hard he tries to behave well! We've got to be filled, to be imbued with the idea that our Father, and very much our Father, is God who is both near us and in heaven. (The Way, 267)
Rest and repose in the fact of being children of God. God is a Father who is full of tenderness, of infinite love. Call him 'Father' many times a day and tell him — alone, in your heart — that you love him, that you adore him, that you feel proud and strong because you are his son. All this implies a genuine programme of interior life, which needs to be channelled through your relationship of piety with God, through these acts (which should be few, I insist, but constant) which will enable you to develop the attitudes and manner of a good son.
I must also warn you against the danger of routine — the real sepulchre of piety. Routine is often disguised as an ambition to do or to embark upon great feats, while daily duties are lazily neglected. When you see this beginning to happen, look at yourself sincerely before Our Lord: ask yourself if the reason why you may have become tired of always struggling on the same thing, is not simply that you were not seeking God; check if your faithful perseverance in work has not fallen off, due to lack of generosity and a spirit of sacrifice. It is then that your norms of piety, your little mortifications, your apostolic efforts that are not reaping an immediate harvest, all seem to be terribly sterile. We find ourselves empty and perhaps we start dreaming up new plans merely to still the voice of our Heavenly Father who asks us to be totally loyal to him. And with this dream, or rather nightmare, of mighty wonders in our soul, we become oblivious to reality, forgetting the way that will lead us most certainly straight towards sanctity. It is a clear sign that we have lost our supernatural outlook, our conviction that we are tiny children and our confidence that our Father will work wonders in us, if we begin again with humility. (Friends of God, 150)
