When the Son of God came to earth he took on a human nature with all the limitations of any other person. But in time that human nature was given all the powers of His divine nature.
To make alive, to have all judgment and all power in heaven and on earth, to have all things in His hands, to have all things subject beneath His feet, to cleanse from sin, and so on, are not created gifts. These are divine, infinite properties. Yet, according to the declaration of Scripture, these have been given to the man Christ. (Hebrews 2:8)
This communication is not to be understood as a way of speaking, or just words about the person according to the divine nature alone, but according to the received human nature. The following three strong, irrefutable arguments and reasons show this:
First, Holy Scripture testifies that what Christ received in time He did not receive according to the divine nature. (According to this nature He has everything from eternity.) But the person of Christ has received attributes in time by reason of and with respect to the received human nature.
Second, the Scriptures testify clearly that the power to give life and to execute judgment has been given to Christ because He is the Son of Man and has flesh and blood.
Third, the Scriptures speak not merely in general of the Son of Man, but also indicate clearly His received human nature, "the blood of Jesus His Son cleanses us from all sin". This is true according to the merit ‹of Christ's blood› that was once attained on the cross. (paragraphs 55-59)
