L1: Who is this man?

The Challenge of this Question

So far, we have laid out the question we seek to answer (Who is Jesus?) and also demonstrated how important this question is. But before moving on to how we will answer this question, it is wise to consider what our posture ought to be as we answer. 
Let’s be clear, friends: we are not in the judge’s seat. We do not sit in judgment over Jesus or his Word. We do not answer this question like a scientist who dissects a dead fish on the table. No! The Lord Jesus is the mighty Judge. He comes to us, and he demands an answer. Consider this warning and promise from Psalm 2:
Now, therefore, O kings, be wise;
    be warned, O rulers of the earth.
Serve the LORD with fear,
    and rejoice with trembling!
Kiss the Son,
    lest he be angry, and you perish in the way,
    for his wrath is quickly kindled.
Blessed are all who take refuge in him!

Psalm 2:10–12 ESV


So, sisters and brothers, let us look to our hearts as we answer this question about who Jesus is. 
We do not demand an answer from God. He reveals Jesus and demands an answer from us. And in this, God reveals our heart. As the Holy Scriptures say: “This is the verdict: Light has come into the world, but people loved darkness instead of light because their deeds were evil” (John 3:19).
Ultimately, there are two ways that we can ask this question:
The first option is to ask the question like Pharaoh. In Exodus 5:2, Pharaoh foolishly thought that he sat in the judge’s chair: “Who is the LORD that I should obey him?" Oh, may God guard our hearts from such death-dealing pride!
Instead, we must ask this question as those seeking to "take refuge in him" (Psalm 2:12 ESV). We must ask this question with a humble joy, rooted in the truth that the Triune God of the Bible delights in making himself known to us. Not because he has to. Not because we earned that right. Not because we were lovely enough to attract his attention. But because this is who he is. He has mercy on whomever he wants to have mercy (Exod 33:19; Rom 9:15).
And so, our answer to this question is about worship. As we consider together who Jesus is, let us worship him. Let us worship–with true wonder and joy–that we, sinners, can know this Jesus. Let us marvel at him, the Treasure whom the Father has shared with us. Let us worship Jesus as we speak and as we listen. Let us worship him as we sit and as we stand. Let us worship him as we gather and as we disperse. For the Father sent the Son “so that by believing [we] may have life in his name” (John 20:31). 
Oh how I pray that through this study God would make us more like the widow who gave everything she had in the temple (Luke 21:1-4). She held nothing back in her love for the Lord. May God work this same wholehearted love for Jesus in us!
What does this kind of love look like in real life? 
John Piper models such loving and joyous worship in this eight-minute section from one of his sermons. Please take some time to watch it and worship Jesus with him.
