Love: “The Word became flesh so that thus we might know God's love”(CCC 458)
How do we know God loves us? Jesus reveals God’s love to us, through what He has said and done, eg forgives us, heals us, teaches us the truth, and ultimately dies for us.
Divine: “The Word became flesh to make us "partakers of the divine nature"” (CCC 460, see DV 2)
Salvation can be seen from three aspects, forgiveness of sins, friendship with Jesus and sharing in the divine nature. In giving ourselves to God, we begin to participate in Trinitarian life, which means we start to share in the divine nature itself. The more we share our life with God (including our sin) the more God will share his divine life with us. The best part is friendship with Jesus. That Jesus personally guides us and helps us in life.
The Incarnation is Jesus being true God and true man like humans in all things but sinless. Not part God, part man, nor an assumed humanity.
Incarnation: “the Church calls "Incarnation" the fact that the Son of God assumed a human nature in order to accomplish our salvation in it.” (CCC 461)
True: “Jesus Christ is true God and true man.: (CCC 464)
Sinless: “like to us in all things except sin.” (GS 22)
Jesus never sinned. His every action was an action of love.
