Hummingbirds are beautiful birds, with amazing and unique attributes. They have been on this earth for millions of years. This imagery is a reminder to praise the Lord continually. In Psalm 96:1-2 King David exhorts us to: "Sing to the LORD a new song; sing to the LORD all the earth. Sing to the LORD, praise His name; proclaim His salvation day after day.". Also, Paul reminds us to "Rejoice in the Lord always. I will say it again, Rejoice!" (Philippians 4:4)
