There is nothing He will not do for us, for He is our Saviour in every sense of the word. He places Himself at our disposal, and in return asks only our cooperation. And he even gives us what we need to do this, for it is such a contradiction with reason that it takes His grace to help us realize this extent of His love, this self-gift of His in the Eucharist. If you believe, you have received His grace as His free gift. The effects of the Eucharist are like the effects of food for our body.
Food sustains life, and the Eucharist sustains the life of the soul.
It gives us the grace we need to deny ourselves and to life for Christ, to live for our Life. The more love we have for Christ, the less self-love we have. The more we love God, the more we can resist temptation, and so the Eucharist strengthens us spiritually. Thus, the Eucharist has the effect of bringing to life the virtues in us so that we can live the life of Christ in us. But just a ordinary food can be effected only when properly digested, so to the Eucharist can only produce its good effects when we are properly disposed to receive it.
