Some thoughts on John 8:1-11, the passage on the woman caught in adultery and brought to Jesus by the ruling religious leaders.
The woman was guilty of breaking the law and deserved punishment as the religious leaders claimed. As events unfolded, it appears Jesus convicted these leaders of their sins, yet, instead of staying and receiving mercy as the woman did, they left with their deserved punishment still hanging over their heads.
Jesus was the only one who could grant mercy. The just penalty of God's justice must be paid, and He alone could and did pay it. He could grant this woman mercy because of what He knew He would do in fulfilling His mission on the earth.
The religious rulers missed out because they desired justice over mercy and ending up condemning themselves.
