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.

No Christian teaching demonstrates that we have a top-down faith more than the doctrine of the Holy Trinity. Scripture teaches that there is only one God. Yet that God exists as three distinct persons: Father, Son, and Holy Spirit. Incomprehensible! It is the type of teaching about which the psalmist declares, “Such knowledge is too wonderful for me, too lofty for me to attain” (Psalm 139:6). We believe in the Triune God without fully comprehending His existence, simply because the Spirit has given us the gift of faith. Our belief in the Triune God came from the top down.

Not only is the concept of the Trinity itself something unique to the Christian faith, but what the Triune God does for us and offers us is also completely unique. Our Triune God invites us into the blessed relationship that is part of His very nature. The members of the Trinity share with us an intimacy that they have enjoyed with each other from eternity. Our Triune God makes us not servants or subjects but blessed members of His family.

Rethinking the Solution to Sin. While not every religion uses the word “sin,” they all embrace the concept. Every religion acknowledges that mankind’s flawed attitudes or misguided actions are a source of pain, both now and potentially in eternity. So, every religion offers a solution: a set of laws, a moral code, a path to more enlightened behavior. What do they have in common? We are to solve sin through human effort. Be better! Try harder! This is the heart of every false religion. Those who correctly understand will never overcome their sins are crushed by guilt. Those who ludicrously believe they have defeated their sin are killed by pride.

True religion offers a better way—one that frees us from guilt and has no room for pride. Jesus teaches that the solution to our sin is not to work harder. It is to trust in the work He has done for us. Salvation comes through Spirit-wrought faith in Christ.

From Jordan’s Shore to Mountain’s Glory: Committed to a Lofty Charge. To whom does the work of salvation belong? Simple question. There is only one Savior. Yet He gives our lives a profound meaning and eternal purpose, by sharing His work with us. He calls us not just to be followers, but to be follower-makers. Jesus asks some—pastors, missionaries, teachers—to do this full time. But ultimately Jesus asks all believers to serve as His ambassadors, sharing the Gospel with whomever He brings into our sphere of influence. This lofty charge requires commitment—a willingness to abandon everything else should faithfulness require it. This is the life-changing revelation for this week. Jesus has committed us to a lofty charge: the privilege to play a role in His saving work.

On Christmas Eve the angel told the shepherds, “I bring you good news that will cause great joy for all the people” (Luke 2:10). One wonders if those words struck those Jewish shepherds as odd. For centuries, God had given special attention to one nation—Israel. There were Jewish religious leaders who taught that only members of that special people would be saved. Not according to the Christmas angel! The birth of the Savior was good news for all people.

Today we celebrate the Epiphany of our Lord. Epiphany comes from a Greek word meaning “reveal.” When the Savior was born, He was first revealed to Israelites: the shepherds, Simeon, Anna. But today, the Lord miraculously guides foreigners across countless miles, so the Savior could be revealed to them as well. How did the magi respond? “They were overjoyed” (Matthew 2:10). Epiphany is sometimes known as “The Gentiles’ Christmas.” We Gentiles (non-Jews) rejoice in the good news that this Jewish baby is not just the Savior of Jews. He is for all people—the Savior of the world.
