Jesus does not have a split personality! That is not meant to be disrespectful but to emphasize what we have already said about Christ; he has two natures united in one person. There is an essential unity to his person even as his two natures remain distinct.
If we don’t understand this we not only feel a bit confused about how to relate to Christ. Can we worship him? Yes, we worship him as Lord and God because he is. Can we come to him as one who knows our sufferings and sorrows who has experienced temptation and difficulty? Yes, he is our elder brother and high priest sharing our nature yet without sin.
But we can also end up making significant errors denying the full deity of Christ or the full humanity of Christ or by making him some kind of composite which undermines Christ’s glory and leads to confusion and error in interpretation of many texts.
So in Section 7 the Confession reminds us to take care that we don’t get confused on this when we look at the Scriptures
Christ executed his work for us IN THE UNITY OF HIS PERSON, however IN THAT UNIFIED WORK each nature was acting harmoniously together according to what was proper to each.
A simple illustration might be to think of Jesus calming a storm as recorded in Matthew 8 and the parallels. As a man Jesus was fully trusting the Father in such a way that he was sleeping in the midst of the storm while the disciples with “little faith” were panicking. As he arose from his sleep he commanded the wind and the waves to be still as the God and Lord over creation itself.
Again he is one person and his natures are acting with one accord at every point, but each does what is proper to itself. His divine nature didn’t sleep and his human nature didn’t have the power in itself to calm the wind and the waves.
So don’t get confused when the Scripture says something like this from Acts 20:28, “Pay careful attention to yourselves and to all the flock, in which the Holy Spirit has made you overseers, to care for the church of God, which he obtained with his own blood.” The divine nature of Jesus did not bleed, his flesh bleed. But the Scriptures can say that “God”, “…obtained (the church) with his own blood” because the person of Christ was divine.
And don’t get confused when you read something like this from John 6:41-42, “So the Jews grumbled about him, because he said, “I am the bread that came down from heaven.” 42 They said, “Is not this Jesus, the son of Joseph, whose father and mother we know? How does he now say, ‘I have come down from heaven’?” Jesus human nature did not pre-exist and come down from heaven but rather Jesus pre-existence was as the Son of God.
Some have been led to deny either the fully divine or human nature of Christ due to such passages. But with a proper Christology (biblical theology of the person and natures of Christ) you can safely navigate many of the so called “problem passages” in the Scriptures with ease.
Just remember your confession!
Westminster Confession Chapter 8.7
VII. Christ, in the work of mediation, acts according to both natures, by each nature doing that which is proper to itself; yet, by reason of the unity of the person, that which is proper to one nature is sometimes in Scripture attributed to the person denominated by the other nature.
 ACT 20:28 Take heed therefore unto yourselves, and to all the flock, over the which the Holy Ghost hath made you overseers, to feed the church of God, which he hath purchased with his own blood. JOH 3:13 And no man hath ascended up to heaven, but he that came down from heaven, even the Son of man which is in heaven. 1JO 3:16 Hereby perceive we the love of God, because he laid down his life for us: and we ought to lay down our lives for the brethren.
