CCC 604 By giving up his own Son for our sins, God manifests that his plan for us is one of benevolent love, prior to any merit on our part: “In this is love, not that we loved God but that he loved us and sent his Son to be the expiation for our sins.”1 God “shows his love for us in that while we were yet sinners Christ died for us.”2
