We are in a world where light and knowledge abound, yet many claiming to be of like precious faith are willingly ignorant. Light is all around them, yet they do not appropriate it to themselves. Parents do not see the necessity of informing themselves, obtaining knowledge, and putting it to a practical use in their married life. If they followed out the exhortation of the apostle, and lived upon the plan of addition, they would not be unfruitful in the knowledge of our Lord Jesus Christ. But many do not understand the work of sanctification. They seem to think they have attained to it, when they have learned only the first lessons in addition. Sanctification is a progressive work; it is not attained to in an hour or a day, and then maintained without any special effort on our part. (2T 472.1) MC VC

Many parents do not obtain the knowledge that they should in the married life. They are not guarded lest Satan take advantage of them and control their minds and their lives. They do not see that God requires them to control their married lives from any excesses. But very few feel it to be a religious duty to govern their passions. They have united themselves in marriage to the object of their choice, and therefore reason that marriage sanctifies the indulgence of the baser passions. Even men and women professing godliness give loose rein to their lustful passions, and have no thought that God holds them accountable for the expenditure of vital energy, which weakens their hold on life and enervates the entire system. (2T 472.2) MC VC

The marriage covenant covers sins of the darkest hue. Men and women professing godliness debase their own bodies through the indulgence of the corrupt passions, and thus lower themselves beneath the brute creation. They abuse the powers which God has given them to be preserved in sanctification and honor. Health and life are sacrificed upon the altar of base passion. The higher, nobler powers are brought into subjection to the animal propensities. Those who thus sin are not acquainted with the result of their course. Could all see the amount of suffering which they bring upon themselves by their own sinful indulgence, they would be alarmed, and some, at least, would shun the course of sin which brings such dreaded wages. So miserable an existence is entailed upon a large class that death would to them be preferable to life; and many do die prematurely, their lives sacrificed in the inglorious work of excessive indulgence of the animal passions. Yet because they are married they think they commit no sin. (2T 472.3) MC VC
