How do we know that Jesus shows mercy to sinners?

The New Testament draws on Old Testament prophecy to demonstrate Jesus's merciful character. In Matthew 12:19, the fulfillment of Isaiah's prophecy highlights that Jesus did not clash with those seeking mercy but rather nurtured them with grace. His interactions with sinners, such as when he allowed His disciples to eat on the Sabbath, showcase His focus on their needs over legalistic scrutiny. His call to the weary, as seen in Matthew 11:28-30, further underscores His enduring kindness and readiness to uplift those burdened by their sin.
