In Heaven Opened, Richard Alleine discusses the nature and blessings of God’s gracious covenant with His people. He outlines in great detail the roles in this covenant of God, Christ, the Spirit, the earth, the angels of light, the powers of darkness, death, and the kingdom. Furthermore, he explains and admires the fruits of the covenant in the believer’s life as it manifests itself in a renewed heart. The book ends with an equally moving exhortation to sinners and saints. See how God graciously opens the vaults of heaven to bless the souls of all those who come to Him in faith.
