Onn Sein was a successful lawyer at age 27 when the Lord called him into the mission field of the poor amongst the natives. He saw the wonderful revival that took place amongst them. However, they were still not lifted from their poverty due to injustice in the economic system. The business of the world focuses on profit maximization, profit before people and keeping wages low. Hence, the rich get richer, and the poor become poorer. Even Christians are sucked into this worldly system that oppresses the poor just like the days of Amos. And God called Amos to speak His judgements to Israel calling for repentance and for righteousness and justice. (Amos 5:12-24).
