Those who are perfect in faith ask God for everything, trusting in the Lord.
They obtain because they ask without doubting and without being double-minded…
Cleanse your heart from doubt, therefore, and put on faith because it is strong…
Consider the doubting mind.
It is wicked and senseless and turns many away entirely from the faith
even though they are very strong.
For this doubting is the daughter of the devil, and acts extremely wickedly to the servants of God.
Despise doubting, then, and gain mastery over it in everything.
Clothe yourself with faith, which is strong and powerful.
For faith promises all things and perfects all things,
but doubt, having no thorough faith in itself,
fails in every work which it undertakes.
Shepherd of Hermas
