Thou shalt not commit adultery. Exodus 20:14.
(SD 62.1)
This commandment forbids not only acts of impurity, but sensual thoughts and desires, or any practice that tends to excite them. Purity is demanded not only in the outward life, but in the secret intents and emotions of the heart. Christ, who taught the far-reaching obligation of the law of God, declared the evil thought or look to be as truly sin as is the unlawful deed.70
(SD 62.2)
When the thought of evil is loved and cherished, however secretly, said Jesus, it shows that sin still reigns in the heart. The soul is still in the gall of bitterness and in the bond of iniquity. He who finds pleasure in dwelling upon scenes of impurity, who indulges the evil thought, the lustful look, may behold in the open sin, with its burden of shame and heartbreaking grief, the true nature of the evil which he has hidden in the chambers of the soul. The season of temptation, under which, it may be, one falls into grievous sin, does not create the evil that is revealed, but only develops or makes manifest that which was hidden and latent in the heart. As a man “thinketh in his heart, so is he”; for out of the heart “are the issues of life.”71 The heart in which Christ dwells, will be so filled, so satisfied, with His love that it will not be consumed with longing to attract sympathy and attention to itself. And through the surrender of the soul to God, His wisdom can accomplish what human wisdom fails to do.72
(SD 62.3)
So long as life shall last, there will be need of guarding the affections and the passions with a firm purpose. Not one moment can we be secure except as we rely upon God, the life hidden with Christ.73
(SD 62.4) 1 I
The nearer we live to Jesus, the more will we partake of His pure and holy character; and the more offensive sin appears to us, the more exalted and desirable will appear the purity and brightness of Christ.74
