We are aware that the order of God requires the exercise of humility, but not of servility of slaves; but a humility that can be associated with undoubted courage and unflinching integrity; at the same time there is no room for pride, self-sufficient pride, that rests solely upon its own capabilities, and refuses to look for the support and countenance of others.--MS 7:91 [MS is the Millenial Star]
John Andreas Widtsoe... since birth control roots in a species of selfishness, the spiritual life of the user of contraceptives is also weakened. Women seem to become more masculine in thought and action; men more callous and reserved; both husband and wife become more careless of each other, and increasingly indifferent to the higher duties and joys of living.
