Remembrance
For Memorial Day, I usually go with a theme about Remembrance, (communion) but here are some ideas for patriotic, or blessing America.
How about why we should Humble ourselves and pray. Or How James and John were upset about being rejected and wanted Jesus to bring fire on the city . . . but Jesus would rather bless.
Or talk about symbols: the meaning of the colors of our flag, and of the christian flag, the In God we trust on our coins, the statue of Liberty, our pledge . . .
Like the song: talk about how the statue of Liberty stands as a tall symbol which make us stand tall and say "I am proud to be an American" The cross stood tall as our symbol to say "I am proud to be a Christian."
Carman has a song that mentions the faith of the founding fathers of America (America Again), it's a great song (mostly talking).
Dave Roever's (survived an explodes grenade in Vietnam) testimonies are excellent, he even has a children's tract with his story.
