Our sanctification
But how shall I know what is the will of God in such and such a particular case? The thing proposed is in itself of an indifferent nature, and so left undetermined in Scripture. I answer: Scripture itself gives you a general rule applicable to all particular cases. The will of God is our sanctification (1 Thessalonians 4:3). It is his will that we should be inwardly and outwardly holy, that we should be good and do good in every kind and in the highest degree of which we are capable. Thus far we tread upon firm ground. This is as clear as the shining of the sun. In order therefore to know what is the will of God in a particular case, we have only to apply this general rule.

23. “But how shall I know what is the will of God, in such and such a particular case? The thing proposed is in itself of an indifferent nature, and so left undetermined in scripture.” I answer, The scripture itself gives you a general rule, applicable to all particular cases. The will of God is our sanctification. It is his will that we should be inwardly and outwardly holy; that we should be good and do good in every kind, and in the highest degree whereof we are capable. Thus far we tread upon firm ground. This is as clear as the shining of the sun. In order therefore to know, what is the will of God in a particular case, we have only to apply this general rule.
