The graces always abound. Receiving Holy Communion worthily brings us graces that affect us both spiritually and physically. Spiritually, our souls become more united to Christ, both through the graces we receive and through the change in our actions that those graces effect. Frequent Communion increases our love for God and for our neighbour, which expresses itself in action, which makes us more like Christ.
A Physical effect is, frequent Communion relieves us of our passions. Priests and other spiritual directors who counsel those who are struggling with passions, especially sexual sins, often urge frequent reception not only of the Sacrament of Confession but of the Sacrament of Holy Communion. By receiving Christ’s Body and Blood, our own bodies are sanctified, and we grow in our likeness to Christ In fact, as Fr. John Hardon points out in his Modern Catholic Dictionary, the Church teaches that “A final effect of Communion is to remove the personal guilt of venial sins, and the temporal punishment[earthly and purgatorial]
due to forgiven sins, whether venial or mortal.”
