The Obligations Imposed on Abraham from Horton’s Systematic Theology

the_christian_faith_hortonGod did, of course, impose obligations on Abraham, but they were the consequence rather than the conditions of his promise.  In some sense, faith may be considered a condition of receiving Christ and all of his benefits, but even in this instance it is contrasted with works.  The works that believers are called to “walk in” are the way of life, not the way to life.  Despite its imperfections, this grateful response can be offered by us precisely because the stability of the covenant depends on Christ’s life of thanksgiving and his guilt offering cancels the sin clinging even to our best works.  While the moral commands continue to indicate the course that our sanctification is to take, it is from the gospel alone that we draw our strength.  Union with Christ is not a goal, but the presupposition, of our new obedience: “If we have died with him, we will also live with him;  if we endure, we will also reign with him; if we deny him, he will also deny us; if we are faithless, he remains faithful— for he cannot deny himself”  (2Ti 2:11-13). p. 617
