The writer of this book has selected thirty-four texts from the Bible and wrote these textual sermons in order to explain how the universal Church, which is the body of believers in Jesus Christ, should be served by Christian leaders and how they can serve the world with justice and righteousness. The Bible is the word of God, which is all sufficient source of knowledge and wisdom. The God of the Bible had implanted the idea of social justice and righteousness through His general revelation for the world and He has given the special revelation of His teaching through His Son Jesus Christ for the universal Church. The Bible teaches ethical monotheism. Its monotheism also includes democratic way that the people are given a right to select virtuous persons from among them. Those virtuous people are appointed by the leaders to serve the people and God. God chooses leaders, such as kings, judges, priests, and heads of the church that they serve Him and the people. Every leader, whether small or great, is accountable to God. An individual, a family, a society, and a nation is established by keeping His righteousness and justice. The author argues that God is more interested in social justice than ceremonial religious life. He demands of His servants to render justice to the helpless persons, such as orphans and widows, and sojourners; and He asks His people to meet every need, like giving food and water, shelter, and medical care and to give words of comfort and hope to the needy. This book would help evangelists and social activists to teach social justice and righteousness from a biblical point of view and reform the society in general. The writer has published other books for propagating the biblical teaching; please refer to his other publications, which are mentioned in this book. This book has helpful suggestions at the end of each chapter for planning devotional service around these themes.
