In our first Believing we take Christ in the Relation of a Saviour, and Teacher, and Lord, to save us from all sin, and to lead us to glory. This therefore importeth that we accordingly submit unto him, in those his Relations, as a necessary means to the obtaining of the benefits of the Relations. Our first faith is our Contract with Christ…And all Contracts of such nature, do impose a necessity of performing what we consent to and promise, in order to the benefits…And in humane contracts it is so. Barely to take a Prince for her husband may entitle a woman to his honours and lands; But conjugal fidelity is also necessary for the continuance of them; for Adultery would cause a divorce… Covenant-making may admit you, but its the Covenant-keeping that must continue you in your privileges.
17th Century English Puritan, Richard Baxter
