‘The only wise God’ deserves all praise, honor, and glory since He is the originator and sustainer of His wonderful plan for redemption. His objective “to bring about the obedience of faith” from among the nations will be realized (Romans 16:26).

Satan is the accuser of Christians who undermines grace and assurance, makes Christians insecure, always feeling we have something to prove and therefore divides the church into those who think they have achieved some merit and goodness and those who despair that they haven’t. This is the one whom the God of peace will soon crush under your feet” (Romans 16:20).

The central question to which the whole New Testament in one way or another is addressed is the question of our relationship, here and hereafter, with our holy Creator: How weak, perverse, estranged, and guilty sinners may gain and guard knowledge of God’s gracious pardon, acceptance and renewal. It is to this question that Christ is the answer, and that all New Testament interpretation of the cross relates.
