Salmos 33

Salmos 33:15

Only [God] can cure our hearts, he who alone created our hearts and perceives all our deeds. He alone has the power to enter into our conscience, touch our thoughts and comfort our soul. And if he does not console our hearts, all that people may do is superfluous and unprofitable. Just as when God comforts and pacifies us again, even if people greatly disturb us with myriad troubles, they will be unable to injure us in anything, for when he strengthens our heart, no one is able to shake it. — HOMILIES ON REPENTANCE AND ALMSGIVING 4:3.17
