An essential part of the Christian confession is that Jesus of Nazareth is “fully God” and “fully man.” If you sometimes wonder why the Nicene Creed and the Definition of Chalcedon are so specific and so detailed, it is because there are numerous ways to slip off the point and into heresy.
One of the easier ways to do this is to imagine Jesus as having a human body, but being “God on the inside.” But no. We confess that Jesus was and is entirely human, and a good way to reinforce this in our minds is to consider what the Scriptures teach about the emotional life of Christ.
