In this work Doolittle exhorts and teaches from Isaiah 61:1, "The Spirit of the Lord God is on me, because the Lord has anointed me to preach good tidings to the meek. He has sent me to bind up the broken-hearted, to proclaim liberty to the captives, and the opening of the prison to them that are bound." This is a thoroughly evangelical work that demonstrates the practical reasons why sinners are bound up by sin and the devil, and need to be delivered from the bondage of a depraved mind and will. He covers reasons such as ignorance, prejudice, love of the world, presumption, despair and a number of others as to why sinners often do not come to Christ. He also expounds on what freedom in Christ is, and how one may obtain being freed by Christ from their chains of sin and wickedness.
