Hold faith and humility fast within you; for through them you will find mercy, help, and words spoken by God in the heart, along with a protector who stands beside you both secretly and manifestly. Do you wish to obtain these things, which are a fountain of life? From the very onset take hold of simplicity. Walk before God in simplicity and not with knowledge. Simplicity is attended by faith; but subtle and intricate deliberations, by conceit; and conceit is attended by separation from God. – from The Ascetical Homilies of St. Isaac the Syrian.
