"That it is such a little thing."
"That it is so hard to obey!"
Ah! What must the little Christian boy do when he finds tares in the field of his heart? What must the little Christian girl do when she finds tares in God's Kingdom in her heart?
I think the best thing to do is to look up to Jesus instantly, and ask Him to conquer the great enemy for you. Say the Holy name Jesus softly to yourself, or out loud if you are alone, Satan, our great enemy, will run away, you will surely find.

"For He shall save His people from their sins."
[XXVIII. The Prodigal Son]
There was a man who had two sons. He loved them both very much, and did everything he could to make them happy.
But the younger son was restless, and got tired of being quietly at home. He had heard something about the world outside, and he thought it must be a very fine place by all accounts.
So one day he asked his father to divide what he had to leave to him and his brother, so that he might do as he liked with his share of it.
