If you greedily eat and drink much, then you will be flesh; whilst if you fast and pray, then you will be spirit. “Be not drunk with wine, wherein is excess, but be filled with the Spirit.” Fast and pray, and you shall accomplish great things. The satiated man is incapable of great works. Have simplicity of faith, and you shall accomplish great things; ” for all things are possible to him that believeth.” Be watchful and zealous, and you shall do great things.

—St. John of Kronstadt, My Life in Christ
