Jesus was born merely human and that he became divine later in his life.?

Jesus earned the title Christ through his sinless devotion to the will of God, thereby becoming the perfect sacrifice to redeem humanity. There are two key points in Jesus' life as stages in Jesus' theosis: his baptism and his resurrection. God had given Jesus his miraculous power and divine authority after Jesus proved his holiness. These concepts are in the Gospel of Mark and in the Pauline epistles.
