In generous kindness and mercy Jesus made a way to have eternal life.  Christians should do good with their lives to bring honor to Him.

Titus 3:

4 But–

When God our Savior revealed his kindness and love, 5 he saved us, not because of the righteous things we had done, but because of his mercy. He washed away our sins, giving us a new birth and new life through the Holy Spirit.[a] 6 He generously poured out the Spirit upon us through Jesus Christ our Savior. 7 Because of his grace he made us right in his sight and gave us confidence that we will inherit eternal life.

8 This is a trustworthy saying, and I want you to insist on these teachings so that all who trust in God will devote themselves to doing good. These teachings are good and beneficial for everyone.
