I'm curious,
@JudgeRightly. Why is that funny to you?
Because I find it amazing the number of Christians who do not know the difference between mercy and grace.
Prodigal son? Grace! Woman at the well? Grace! Woman caught in adultery? Grace! He didn't have to preach it, He lived it.
Yes, the Bible says "grace and truth came through Jesus Christ."
That's a given. We don't dispute that.
But that has nothing to do with what was stated.
What was stated was:
Paul's use of the word 'grace' in his thirteen epistles: 90+
Times that Jesus is quoted using the word 'grace' during His earthly ministry: 0
Jesus sent Paul.
It's kind of hard to preach something if you never use the word for it.
On the other hand, the Gospels speak of law, commandment, ordinance, regulation, and Moses many dosens of times, frequently by Christ's own words. In fact, the word grace is only mentioned 4 times in the gospels, once in Luke 2:40, which says "the grace of God was upon [Jesus]," and four times in John, once in 1:14, "the only begotten of the Father, full of grace and truth," twice in 1:16, "and grace for grace," and once in 1:17, "but grace and truth came through Jesus Christ."
Remember, John was not written until later, WELL AFTER Paul came on the scene with his gospel given to him by Christ Himself, and certainly long after the Jerusalem Council (around 47 AD). John was likely written around 60 AD. More than enough time for the understanding of Paul's dispensation of grace to make its way into the minds of the Gospel authors, so it makes sense for John to write about Jesus bringing grace to the world.
Now, specifically regarding the latter two examples you gave:
With the woman at the well, she was a Samaritan woman, and according to the Jews, Samaritans were unclean, according to the law of Moses.
WIth the woman caught in adultery, the Pharisees brought her before Christ for Him to judge her according to the law of Moses.
The context is law.
Grace has no part in the law.
MERCY, on the other hand, has plenty to do with the law.
To make this simple:
Grace is getting something that one does not deserve.
Mercy is NOT getting something that one DOES deserve.
In both of the latter examples, BOTH WOMEN were guilty of violating the law, and at least in the latter example, and arguably in the former, Jesus showed mercy to each of the women. They did not receive the punishment they deserved.
And regarding the parable of the prodigal son, which, while it is specifically teaching a specific lesson, again, the context is the law.
Specifically, the son says to his father, "I have sinned . . . and am no longer worthy to be called your son." He deserved to be cut off. But His father did not cut him off. He showed mercy to his son.
Basically, NONE of the examples you gave were about grace. They were about mercy. Their context was law, not grace.
