“None of Adam’s guilty race could perform a single duty corresponding to the purity and extent of the holy law, far less an obedience absolutely perfect in parts, degrees and continuance. But without such a righteousness, none of them could ever be entitled to eternal life. The unrighteous shall not inherit the kingdom of God. Jesus Christ, therefore, the Surety of elect sinners, yielded to the law as a covenant, in their room, a righteousness fully commensurate to its high requirements”.
-John Colquhoun, from his , “Sermons on Important Doctrines”,p.155
