Romans 1:8, 11-12 First, I thank my God through Jesus Christ for all of you, because your faith is being reported all over the world. I long to see you so that I may impart to you some spiritual gift to make you strong— that is, that you and I may be mutually encouraged by each other’s faith. 

Faith not only makes us strong and encourages us when shared, but it is also contagious and conspicuous.
