175. External things of the mind, that are of worship, are: 1. Thinking and meditating about God, heaven, eternal life, and salvation; 2. Reflecting upon one's thoughts and intentions, to see whether they are evil or good, and reflecting that the evil ones are from the devil, and the good ones from God; 3. Being averse, in one's mind, from talk about ungodly, obscene, and filthy things; 4. In addition to the thoughts there are also affections that reach a man's sight and feeling.
