12 Guarding himself at all times from sins and evil ways, whether from thought, tongue, hands, feet, or from self-will and the desires of the flesh, 13 let him consider that he is always and at all times being watched by God, and that God’s gaze sees his deeds in every place, which the angels report at all times.
14 The Prophet points this out to us when he shows just how our thoughts are always present to God, saying:
You search the minds and hearts, O God. (Ps 7:10)
15 And also:
The Lord knows the thoughts of all humanity. (Ps 94:11)
16 And he also says:
You have understood my thoughts from afar. (Ps 139:3)
17 And,
Human thought will confess you. (Vulgate Ps 75:11)
18 Therefore, so that he might take care concerning his own perverse thoughts, let a sensible brother always say in his heart:
Then shall I be blameless before him
if I keep myself from my own iniquity. (Ps 18:24)
