Shepherd of Hermas

Put away doubting from you and do not hesitate to ask of the Lord, saying to yourself, "How can I ask of the Lord and receive from Him, seeing I have sinned so much against Him?" Do not thus reason with yourself, but with all your heart turn to the Lord and ask of Him without doubting, and you will know the multitude of His tender mercies; that He will never leave you, but fulfil the request of your soul. For He is not like men, who remember evils done against them; but He Himself remembers not evils, and has compassion on His own creature. ... For those who doubt regarding God are double-souled, and obtain not one of their requests. But those who are perfect in faith ask everything, trusting in the Lord; and they obtain, because they ask nothing doubting, and not being double-souled. For every double-souled man, even if he repent, will with difficulty be saved.

Instead of lands, therefore, buy afflicted souls, according as each one is able, and visit widows and orphans, and do not overlook them; and spend your wealth and all your preparations, which ye received from the Lord, upon such lands and houses. For to this end did the Master make you rich, that you might perform these services unto Him.
