I appreciate it when folks post hymns or Psalms they find on Youtube. Its really edifying to listen to them as they bring our focus to what God has done, who He is, etc. The Acapella Youtube Psalm that Andrew posted was a blessing. It prompted me to look for more.
Here's one that I found that really reminds me of God's greatness. Sometimes when I read things in the Bible, like "...and God said, Let their be _____, and there was_____" I need to be reminded of just what happened when God spoke the word - mind boggling! Last time I went whale watching I looked at the oceans and thought about God gathering all the waters together - try doing it, its no small task!
What YouTube Psalms have been a blessing to you? Let's see how many we can collect.
PS. I wouldn't be upset if you added some God honoring Youtube hymns as well. That's one rabbit trail I'll gladly go on.
