Tremble, Or Worship?

Psalm 114 is pretty short, just eight verses. In my Bible the heading of this psalm is "Tremble at the Presence of the Lord."  The last two verses say:

"Tremble, O earth, at the presence of the Lord,
    at the presence of the God of Jacob,
 who turns the rock into a pool of water,
    the flint into a spring of water."

I was reading it and wondering what it all meant. Tremble at God's presence? I understand that, if we are thinking about how powerful, mighty and completely different God is from us. But if the Bible is all about God, and more specifically all about Jesus, in one way or another, where is that connection in this psalm, especially the last two lines? Is there something besides simply a picture of what God can accomplish through his power?

So I gave the last two lines more thought, and began to understand something. Rock into water. Flint into water. An object that is clearly one thing being transformed into something completely different. A sinner, lost under the judgment of God, transformed into someone who has received God's grace. A sinner who hates God, transformed into a person who still sins but who has also tasted God's mercy and loves God as a result.

As I said, I understand the reasons why the psalm might lead a person to tremble before the Lord, but I can also see worship as an equal, and perhaps more precious, response. May you know the Lord's transforming power in your heart and life. Amen.
