Promises, Obligations and Warnings in the Garden

Westminster Confession of Faith: Chapter 7:1-2 Of God's Covenant with Man

1. The distance between God and the creature is so great, that although reasonable creatures do owe obedience unto Him as their Creator, yet they could never have any fruition of Him as their blessedness and reward, but by some voluntary condescension on God's part, which He hath been pleased to express by way of covenant.
2. The first covenant made with man was a covenant of works, wherein life was promised to Adam; and in him to his posterity, upon condition of perfect and personal obedience.
   Chapter 19: 1. God gave to Adam a law, as a covenant of works, by which He bound him and all his posterity to personal, entire, exact, and perpetual obedience, promised life upon the fulfilling, and threatened death upon the breach of it, and endued him with power and ability to keep it.
