Summary: David sees the whole earth worshiping God. He recounts a defining act, when God parted the waters for His people to cross. Even though the relationship isn't perfect on humans' ends, God still offers discipline, mercy, and renewal. David finishes by extending an invitation to that same relationship.
Response: God really is worthy of all this praise. So many times, I'll go through the motions, but I don't want to be desensitized to God's greatness.
