Verses and Fathers Sayings

But the ones that fell on the good ground are
those who, having heard the word 
with a noble and good heart, keep it 
and bear fruit with patience.

Luke 8:15  

Observe your thoughts, and beware of what you have in your heart and your spirit, knowing that the demons put ideas into you so as to corrupt your soul by making it think of that which is not right, in order to turn your spirit from the consideration of your sins and of God. 

Abba Elias
