What does the Bible say about why Jesus came?

According to Isaiah 61, Jesus came to preach good tidings to the meek, bind up the brokenhearted, proclaim liberty to the captives, and comfort all who mourn. This mission is confirmed in the New Testament, specifically when Jesus Himself reads this passage in Luke 4, identifying it as a fulfillment of His purpose. The essence of His coming was not merely to provide an example of moral living, but to serve as a successful redeemer, achieving salvation for His elect through His death and resurrection.
