COVENANT, in Theology, is used analogically to designate the gracious engagement on the part of God to communicate certain unmerited favours to men in connection with a particular constitution or system through means of which these favours are to be enjoyed. Thus the Covenant of Grace indicates God's engagement to confer salvation on all who truly believe, and the Covenant of Works his engagement to bestow eternal happiness on all who perfectly obey. The Covenant of Redemption has reference to the engagement between the Father and the Son, whereby the Father secured a certain number of redeemed, and the Son engaged to be their surety.
