Have you heard the song "go tell it on the mountain (over the hills & everywhere!), go tell it on the mountain, that Jesus Christ was born." ?
Jesus, himself, said that we are to go & make disciples of all nations. Yet, many folks don't know what to say or how to say it.
I think there is a reason he said let the little children come to him too. They get it! If evangelism isn't your thing, listen to my 5 year old simply sharing the good new of Jesus. If she can, I know you can too. (and try to have the excitement that she has about the Holy Spirit, can you?)
Matthew 28:19 -- Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit.
Matthew 18:3 -- And he said: "I tell you the truth, unless you change and become like little children, you will never enter the kingdom of heaven.
