How We Will Be Saved on the Last Day.
This is the bread that came down from heaven, says the Lord Jesus, and he assures us that whoever eats him will not die forever. This means that whoever receives Jesus in this Sacrament of Love with dignity will not only maintain spiritual life on earth, but also their souls will never die but live forever. Communion gives immortal life for the soul and body. It is therefore the pledge of the future resurrection and eternal life.
There is no measure for the effectiveness of Holy Communion for our souls. Communion is for the spiritual world what is food for the natural world. As fleshly food renews our nature, so does the Divine Food, which renews and purifies our nature to make it consistent and joined with him.
The Lord Jesus will fortify your souls, he will cleanse them, he will slowly change them in him, so that you may be perfectly one with him, that love may change you here in him. The Lord Jesus, by connecting with the soul, gives it a spiritual life. That is why he said that he came to make souls live and life would be more abundant. And he says the same words when he comes to souls in Holy Communion. Therefore he instituted the Eucharist to keep this spiritual life in us, so that he could multiply it in us more and more. He helps us grow more and more in God’s love, and in all Christian virtues. He helps us overcome ourselves for more and more frequent and perfect deeds. Receive Holy Communion; put fire in your heart, which alone will do the work of conversion and your sanctification; warm up your cold hearts, and light them with love, and change the worldly man into a saint.
