You must keep your memory clean and pure, as it were a wedlock chamber, from all strange thoughts, fancies and imaginations, and it must be trimmed and adorned with holy meditations and virtues of Christ's holy crucified life and passion: That God may continually and ever rest therein.

The proof of spiritual maturity is not how pure you are but awareness of your impurity. That very awareness opens the door to grace.
In the book of Colossians, it talks about that because of what Christ did, we are pure. We are without judgment on ourselves. And only through him can we do something like this.
I would sooner be holy than happy if the two things could be divorced. Were it possible for a man always to sorrow and yet to be pure, I would choose the sorrow if I might win the purity, for to be free from the power of sin, to be made to love holiness, is true happiness.
He came to deliver us from our sinful dispositions, and create in us pure hearts, and when we have Him with us it will not be hard for us. Then the service of Christ will be delightful.
Become pure in heart. The pure in heart shall see God. Here, then, is one opening for soul-culture--the avenue through purity of heart to the spiritual seeing of God.

The man whose blood is pure has nothing to fear. So he whose spirit is purified and sweetened becomes proof against these germs of sin. "Anger, wrath, malice and railing" in such a soil can find no root.

God only requires of his adult children, that their hearts be truly purified, and that they offer him continually the wishes and vows that naturally spring from perfect love. For these desires, being the genuine fruits of love, are the most perfect prayers that can spring from it. It is scarce conceivable how strait the way is wherein God leads them that follow him; and how dependent on him we must be, unless we are wanting in our faithfulness to him.
There is no faithfulness like that which ought to be between a guide of souls and the person directed by him. They ought continually to regard each other in God, and closely to examine themselves, whether all their thoughts are pure, and all their words directed with Christian discretion. Other affairs are only the things of men; but these are peculiarly the things of God.
