“The saying is sure and worthy of full acceptance, that Christ Jesus came into the world to save sinners. And I am the foremost of sinners; but I received mercy for this reason, that in me, as the foremost, Jesus Christ might display his perfect patience for an example to those who were to believe in him for eternal life.” (1 Timothy 1:15-16)
“Since justice insists that all people get their due, and since mercy implies that at least some receive what is not their due, how can the two claims avoid contradiction?
The answer lies in the biblical understanding of our relation to God. He does not owe us our existence but grants it as sheer miraculous gift. There is nothing we could possibly do to compensate for this gift, to make it something deserved – not even to return it. We would be totally indebted even if we were unfallen. Sin hugely magnifies our obligation to the triune God. His deliverance of us from bondage through Israel and Christ and the church makes the debt absolute.
In the deepest sense, therefore, God’s mercy precedes his justice and serves as its very basis.
His judgement is but the enforcement of his mercy: God insists that we live by the same merciful measure wherein we have been created and redeemed. [Author JRR] Tolkien repeatedly demonstrates his understanding of this profound paradox that mercy is not contrary to justice but the true realization of it. Over and again we encounter characters who have done wrong and who deserve punishment, but who receive justice in the form of mercy – as their bad deeds often issue in surprisingly good things.” (Ralph C. Wood, The Gospel According to Tolkien, pp 96-97)
“Mercy triumphs over judgment.”
