The most important reason for Christ’s coming was that people might know how much God loves them.

“The most important reason for Christ’s coming was that people might know how much God loves them. Further knowing in this way the extent of God’s love for them, people might begin to burn with love for HIm who loved them first, and following Christ’s commandment and example, they might love their neighbour. Christ, in loving people who were not close to him but wandering far from him, has become the neighbour” (De Cat Rud 4.8)
