My wife and I (and sometimes others) have felt called to carry a red, yellow, and blue flag on the streets of Nashville for the past 7 years.  It is the official flag of The Salvation Army:  The red represents the blood of Jesus; the yellow stands for the fire of the Holy Spirit; and the blue reminds us that we are called to follow and obey the living, resurrected Jesus Christ in our daily lives.

We recently carried the flag a couple of miles up Dickerson Road to Jodi and Loretta’s newly purchased mobile home. (They are a regular part of The Salvation Army Berry Street Worship Center and were homeless 4 years ago.) We prayed and dedicated their new home to God.
On our way Ernie prayed for divine encounters. Almost immediately a guy in a red pickup truck stopped on the road, rolled his window down, and said: “I grew up in The Salvation Army in New York!” We got to invite him to Berry Street and he said he would come. We had never seen him before, but before he drove away he said: “Thanks for what you are doing! I love you guys!”
Then Rufus yelled at us and he and Scott walked across busy Dickerson Road. Rufus worked as a bell ringer for us one Christmas season. Rufus told us that Scott was homeless and wanted to change his life. We got to encourage both of them, pray with them, and give Scott some leads for recovery and housing. He, also, said he would come visit Berry Street.
Several people honked and waved at us along the way. And a few people asked us about the flag.  It was a real adventure!
