When missionaries or European explorers came into contact with foreign lands that had not been affected by the gospel, they found similar appalling practices—with baby girls, in particular, being the targets. For example, two Norwegian women missionaries in the late-nineteenth century—Sofie Reuter and Anna Jakobsen—found infanticide of little girls a common practice in China…
However, in the last two centuries, because of the modern missionary movement, the lives of women have been greatly improved in scores of countries and hundreds of tribes as the gospel has taken root in those cultures. Take the two courageous missionaries mentioned above as an example. Reuter and Jakobsen would daily comb the abandonment places to save Chinese girls from sure death. They would then rear these girls and disciple them into the Christian faith.
