Shall one who is seeking for glory, honor, immortality, eternal life, form a union with another who refuses to rank with the soldiers of the cross of Christ? Will you who profess to choose Christ for your master and to be obedient to Him in all things, unite your interests with one who is ruled by the prince of the powers of darkness? “Can two walk together, except they be agreed?” Amos 3:3. “If two of you shall agree on earth as touching anything that they shall ask, it shall be done for them of My Father which is in heaven.” Matthew 18:19. But how strange the sight! While one of those so closely united is engaged in devotion, the other is indifferent and careless; while one is seeking the way to everlasting life, the other is in the broad road to death. 1TT 576.2
Hundreds have sacrificed Christ and heaven in consequence of marrying unconverted persons. Can it be that the love and fellowship of Christ are of so little value to them that they prefer the companionship of poor mortals? Is heaven so little esteemed that they are willing to risk its enjoyments for one who has no love for the precious Saviour? 1TT 577.1
The happiness and prosperity of the married life depend upon the unity of the parties. How can the carnal mind harmonize with the mind that is assimilated to the mind of Christ? One is sowing to the flesh, thinking and acting in accordance with the promptings of his own heart; the other is sowing to the Spirit, seeking to repress selfishness, to overcome inclination, and to live in obedience to the Master, whose servant he professes to be. Thus there is a perpetual difference of taste, of inclination, and of purpose. Unless the believer shall, through his steadfast adherence to principle, win the impenitent, he will, as is much more common, become discouraged and sell his religious principles for the poor companionship of one who has no connection with heaven. 1TT 577.2
God strictly forbade the intermarrying of His ancient people with other nations. The plea is now offered that this prohibition was made in order to prevent the Hebrews from marrying idolaters and forming connections with heathen families. But the heathen were in a more favorable condition than are the impenitent in this age, who, having the light of truth, yet persistently refuse to accept it. The sinner of today is far more guilty than the heathen, because the light of the gospel shines clearly all around him. He violates conscience and is a deliberate enemy of God. The reason which God assigned for forbidding these marriages was: “For they will turn away thy son from following Me.” Deuteronomy 7:4. Those among ancient Israel who ventured to disregard the prohibition of God did it at the sacrifice of religious principle. Take the case of Solomon for example. His wives turned away his heart from his God. 1TT 577.3
