How do we know that mercy is important in Christianity?

Mercy is a foundational aspect of Christian teaching, illustrated in Luke 10:37 where Jesus tells the lawyer to 'go and do likewise' after showcasing the Samaritan's compassion. This parable not only demonstrates the importance of showing mercy to those in need but also reveals our profound need for mercy from God due to our inability to fulfill the law's demands. In acknowledging that we are all in need of grace and compassion, we see that our Christian duty is not only to receive mercy but also to extend it to others, regardless of their background or circumstances. This understanding aligns with sovereign grace theology, which recognizes our need for Christ's righteousness and mercy.
