Hi, @ssuttle1! Thanks for this good question. As a worship leader, one of the great burdens I have is to choose words that will both be sung and said in our public worship. That’s a huge responsibility as what we say, the way we sing/say it (sitting, standing, fast or slow tempo,etc.), and when we sing/ say it will shape us as worshippers and colour how we view God. This, in turn, effects our approach to him and how we relate to Him. So, no, I don’t think you’re being too legalistic, and I would hope that your own worship leaders would be not only musically discerning when they choose songs but also theologically discerning!
I have found that there is place in the worship service for all types of songs: the rich hymns of the past (and the familiar tunes that go with them!), newer hymns, and, what sometimes is referred to as ‘praise choruses’. That is, songs that are a bit simpler and repetitive, but give us time and space to reflect upon a specific character attribute of God.
I think Hillsong has put out some wonderful music, and we use a good bit of it in our worship, but the line you mentioned in ‘What a Beautiful Name’ is one that has also niggled at me as well! Though I wanted to do the song because of the spectacular bridge (‘Death could not hold you…’), I kept not doing it because of the line you referenced. However, for me, it’s the first part of it that gets to me. It just seems so…wrong…to assert that God didn’t want to be without us…like he was lacking something or lonely or bored. God does not need us, and I don’t want to proclaim otherwise.
The second part of the line you mentioned doesn’t necessarily bother me, as I understand it as it highlighting just one of the reasons Jesus was born…the Word became flesh…the Son became incarnate. After all…
He came down to earth from heaven
Who is God and Lord of all
And His shelter was a stable,
And His cradle was a stall:
With the poor and mean and lowly,
Lived on earth our Saviour holy.
Jesus did come ‘to save His people from their sins’, thus, Jesus himself, being God in the flesh, is often understood as heaven coming down…a heavenly invasion of earth! But I can see how the line can be understood to be asserting that Jesus brought all of heaven to earth. That, like you said, unfortunately remains to be seen.
But after I thought about it for a while and chatted to some other people, the full line sits with me a little better now. Because it is true that God, for whatever reason, loves us and thought humanity worth saving. So on some level, He didn’t want humanity to be completely separated from Him (i.e. want ‘heaven’ without us), so the Son, that little bit of heaven, came to earth to sort things out (i.e. Jesus, you brought heaven down). God brought salvation down to us. Or, as Charles Wesley put it…
Mild, he lays his glory by
Born that man no more may die
Born to raise the sons of earth
Born to give them second birth
What a ridiculous, marvellous, overwhelmingly humbling, beautiful truth! All praise and thanks to God!
