Dr. Jaerock Lee's second biblical figure series My Chosen Servant Jacob, Descendant of Abraham My Friend was published on April 17, 2016, and it has sold very well. Following the first series Abraham the Friend of God, this book has been greatly loved by many readers and was ranked first in weekly bestsellers of religious books in Kyobo Book Centre.

Why did God choose Jacob, who was a deceitful man, as father of the nation of Israel? Jacob and his twelve sons continued the genealogy of Abraham, the forefather of faith. In their lives is the heart of God who chose them because He loved them and who refined them to give them blessings.

This book has two parts that includes 13 chapters. It starts with Jacob coming forth with his hand holding on to the heel of his elder brother Esau. It continues to describe events of his life such as taking the blessing of the birthright of the firstborn and continuing Abraham's genealogy. Additionally, it explains why Esau lost his birthright of the firstborn; why Judah, who was Jacob's fourth son, received the blessing of a firstborn instead of Reuben and why Joseph was sold to Egypt as a slave.

This book explains the spiritual meanings of the names of Jacob's twelve sons and the twelve tribes of Israel. The book further explains the correlations between these meanings and their measures of faith, the difference between Jacob's twelve sons and Israel's twelve tribes, and the difference between Jesus' twelve disciples and the Lord's twelve apostles.

This book illustrates the love of the Triune God that has been shown from the Old Testament times and will continue to be manifested until the Lord comes back again. It helps the readers realize the love of our faithful God towards mankind and encourages them to run more earnestly towards New Jerusalem as Abraham's descendants.
