Faith is not for discussion but to be kept because it contains the whole plan of God, whatever God wants us to receive of Him and practice. In this book you will see that the objective faith must be wrought into our inner being to become our subjective faith. 
This happens when we believe, when we appropriate all that God has planned and revealed to us.
Dong Yu Lan shows very clearly that God also expects all His children whom He called to be those who promote the faith. For that, we need to use simple and practical ways as mentioned in this publication. Even if you have recently received the Lord, you can apply these words in your life.
