The Son of God took on flesh for two reasons: to be our substitute and our sacrifice. You see, when God created mankind in his image, his desire was that we would live holy lives, full of love for him and our fellow man. When mankind fell into sin, that became impossible. So, the heavenly Father sent Jesus. He is the only human being to keep all of God’s law perfectly. He did that as our substitute. Through faith, we claim his perfection as our own. But we needed another gift—one who could pay for the sin we had committed. And so, the Son of God became human for another reason—so that he might die as the sacrifice for our sins, removing that barrier between us and a holy God.
Understanding we needed both—substitute and sacrifice—helps us better understand Jesus’ saving work. That work includes more than Jesus’ death on the cross. Jesus saving work began the moment he was born under the law and obeyed it. This week, we thank God that Jesus served us in both these much-needed ways!

When a child asks a sibling to do something, there isn’t much certainty as to the results. The sibling might simply ignore the request. However, if that same child goes to a brother or sister with “Dad said so,” it’s a very different story! Now the father’s authority is behind the child’s request.

As believers carry out gospel ministry, encouraging others to turn to Christ in repentance, people might push back. “What gives you the right?” Maybe we ask that question ourselves. “I’m far from perfect. So, what gives me the right to talk about things like sin?” This week we are given the answer to that question. “Dad said so.” When our God calls us to do ministry, he also gives us authority. In calling us to ministry, God isn’t asking us to share our advice or our opinion or even our values. We are sharing God’s own authoritative Word. Gospel ministry is conducted by believers but with God’s own authority behind the effort.

Authority is the power to determine what happens, the ability to give direction or even commands. Authority is limited. Authority is limited in duration. Parents have authority over their children until they grow up and move out. Authority is limited in scope. A governor has authority over the people of his state only, not the neighboring state. Authority is limited by levels. A manager has authority over employees unless the company owner—a higher authority—demotes him. Authority is limited in duration and scope. It is limited by higher levels of authority.

This week we see that there is one man—only one!—who has absolute authority. There is no one, not even the demons, who is outside His authority. As the Son of God there is no higher authority than Jesus. And His authority is everlasting. But here is the best part of this epiphany: Jesus graciously uses His absolute authority for our benefit and blessing.

Our God establishes earthly governments.
