Teen Church Choir Music?

I am part of an Evangelical Presbyterian church in Michigan. I am trying to help my teen choir director find some music. We are a group of about 60, with Sopranos 1 and 2, Altos, Tenors and Bes. I am looking for a song that we could sing maybe at a Christmas concert, but it does not have to be Christmas. We would like it to be more contemporary (examples Nichole Nordman, MercyMe, Chris Tomlin). It does not have to be sung by a choir, and we do not need a link to sheet music. We would just like an inspirational song that teens aged 13-18 can sing.
