Boundless is published by Focus on the Family and has lots of great stuff in it, though often from a Protestant perspective, in accord with the organization's Statement of Faith.
Recently they published an article extolling the Liturgy of the Hours!
Be careful with those historic and traditional forms of Christian prayer. They'll lead you away from your Protestantism.
Making the article personally interesting to me, the author, the Rev. Jim Tonkowich has a degree in philosophy from Bates College, which is what I studied, and where I almost studied it. He's also President of the Institute on Relgion and Democracy in Washington, D.C. When I lived in Washington, the guy who was briefly my roommate worked there.
