All the saints in heaven, and all true Christians on earth, are one body and one spirit; that is why the prayer of believers is heard so easily, so speedily, so truly, in heaven, and why there is so much to be hoped for from calling upon the saints. But in order that our prayers should always be speedily and easily heard by the saints, we must have their spirit – the spirit of faith and love for God and our neighbor, the spirit of meekness, humility, abstinence, purity and chastity, brave valiant, thirsting after righteousness, the spirit of compassion – heavenly, and not earthly.

St. John of Kronstadt
