_In Heart._ We should keep our heart free from impure thoughts and
desires. [Matt. 5:8+, Prov. 4:23+, Ps. 51:10] God judges us by the state
of our heart. [I Sam. 16:7] Unchaste thoughts must not be delighted in
nor harbored, but subdued and stamped out. They poison the soul. They
are themselves a transgression of this commandment, [Matt. 5:28+] and
they lead to further transgressions of it by word and deed.

IN WORDS. We must avoid immodest conversation, unchaste words, vile

6:19, 20+] and they dare not be given over to sin and impurity. [Rom.
6:13] We should remember that God sees even in secret, and knows all our
actions. [Ps. 139:1-12]

_Impurity_ of heart and life will not go unpunished. [I Cor. 3:16, 17+,
Gal. 5:19-21+] It is often followed by the most dreadful consequences: a

public shame, dreadful disease and an untimely death.

_To Keep ourselves Pure_ we should watch and pray, [Matt. 26:41+] avoid
idleness, evil company, bad books and papers, indecent songs and
pictures, immoral plays, intemperance in eating and drinking, and all
that would incite to impurity. We should keep our minds occupied with
