How can God have mercy on us sinful wretches? The story of David and his sin against Bathsheba, Uriah, and most of all God (2 Sam 11-12), tells us of how God’s mercy extends further than we could have imagined. This was adultery and murder — not something God could just “wink” at. In fact, God cannot wink at any sin. However, in the Mosaic system God had set up a system of sacrifice that allowed for the forgiveness of various sins. Thus, people would bring a sacrificial animal for this purpose. But what is most interesting and important for us in this story is that not every kind of sin was forgivable in the Mosaic system. Adultery and premeditated murder, in this case, had no sacrifice for sin.
In 1 Sam 12, Nathan the prophet comes along and tells David the parable about a certain man and his beloved little lamb. And then he explains how this lamb was stolen from his master and killed by an evil neighbor. Upon hearing all this, David pronounces judgment: “That man deserves to die.”
“You are the man,” says Nathan. The prophet then declares everything God had done for David and yet how David had despised the word of the LORD and done what is evil in his sight. And when David hears this, he confesses. “I have sinned against the LORD.” And Nathan replies, “God has taken away your sin, you are not going to die.” What? How could he say that? There would still be consequences for David. But he had received forgiveness. How could this be?
As mentioned before, in the Mosaic system, there was no sacrifice for adultery, no sacrifice for murder. In short, there was no way of dealing with this extent of pollution. There was really no way for David to be forgiven, nothing that would allow him to be right before. Within the Mosaic system, David was a dead man. The King of Israel, the people of God, stood condemned — accountable to die. And yet God declares that he is forgiven. What is this? This was clearly a ‘new mercy’, a new kind of forgiveness. In Psalm 51, we read there was no “desire for sacrifice.” And indeed, for there was no sacrifice to bring.
God was going above and beyond what had been demonstrated before. This was not a mercy that was shown to Eli and his house, or to Saul and his house. This was something new — and amazing. And thus David could say, “Blessed is the man whom the LORD does not impute iniquity” (Ps. 32.2) and Paul :
…just as David also speaks of the blessing of the one to whom God counts righteousness apart from works: “Blessed are those whose lawless deeds are forgiven, and whose sins are covered; blessed is the man against whom the Lord will not count his sin (Rom. 4:6-8).
God was slowly revealing himself and the great extent of his love for us. Here is a mercy greater than which could never be conceived! Such was God’s love for David (and all the elect) that he would see to it that there would be a way of forgiveness. And at the proper time, God sent his only begotten Son to become the lamb who would be slain for the forgiveness of all our sins.
Oh how great is the love and mercy of God. And yet we see how God slowly reveals himself overtime, through redemptive history. This is the God we worship — one who reveals himself in stories like this.
