In this way, we "do not let the left hand [represented by 'self'] KNOW what the right hand [represented by good works] is doing" -Matthew 6:3, lest "self" claims those works as its own.
"You see, although there appears to be no trace of life in Me, in reality, it is present in its fullness in each and every Host. But for Me to be able to ACT UPON A SOUL [OR: to be able to bestow gifts, do miracles or good works through a soul], the soul must have faith. O how pleasing to Me is living faith!" [living faith in the Holy Eucharist!] (Our Lord Jesus said to Sister Faustina as recorded in her Diary, #420.)
