A collection of fifteen articles by colleagues and former students of Professor Willis of Abilene Christian University. The papers deal with the topic of worship from a variety of perspectives and, in different connections, with the life and thought of ancient Israel. These include the participation of foreigners in the worship of ancient Israel, the prophetic critique of the cult, the tradition of the construction of the Jerusalem temple, women and prayer in the Deutero-canonical literature, various ethical aspects of worship and the value placed on the internal dynamics of worship offered to God, the Psalms and ancient Near Eastern mourning customs, and some of the implications of the Old Testament tradition regarding worship for contemporary communities of faith. A select bibliography of Willis's writings is also included.
