The infinitude of the mercy of God is either the most welcome or easiest to digest for the postmodern world. Mercy has been defined as the refusal to dispense the justice deserved to the one to whom it is deserved. To the one who is absolutely and obviously guilty, judicial fairness is dismissed and forgiveness is poured out in abundance. As A.W. Tozer writes:
The mercy of God is infinite too, and the man who has felt the grinding pain of inward guilt knows that this is more than academic. “Where sin abounded, grace did much more abound.” Abounding sin is the terror of the world, but abounding grace is the hope of mankind. However sin may abound it still has its limits, for it is the product of finite minds and hearts; but God’s “much more” introduces us to infinitude. Against our deep creature sickness stands God’s infinite ability to cure.
The truth that there is no sin committed against God or others that cannot be forgiven through Christ’s sacrificial death is a biblically-based fact and a bedrock of Christianity. It liberates the guilt-ridden soul from the prison of despair and shame, setting it free to bask in the beautiful and freeing grace of Christ. Infinite mercy woos the heart that has received such clemency to do the same with the smaller, more finite offenses committed against us.
How should I respond to the infinite mercy of God? This answer is found in the parable of the unforgiving servant in Matthew 18:30-35. When the servant who had been granted leniency for his exorbitant debt refused to do the same for a fellow servant who owed an extremely smaller balance, he was taken by the master and thrown into prison until the impossible debt had been paid. This parable was meant by Jesus to represent the mercy of God in the lives of those whom His mercy has been infinitely allotted. His point is clear that the objects of God’s infinite mercy should be unequivocally disposed to administering the same (Matt. 5:7).
If I genuinely caught a glimpse of this truth and began to display this mercy to others, hostility within and without would dissipate, permitting me to reflect the beautiful glory of God as was His intention.
