Systematic Theology: An Introduction to Biblical Doctrine book by Wayne A. Grudem

The Christian church has a long tradition of systematic theology, that is, of studying biblical teaching on centrally important doctrines such as the Word of God, redemption, and Jesus Christ. Wayne Grudem's bestselling Systematic Theology has several distinctive features:

A strong emphasis on the scriptural basis for each doctrine
Clear writing, with technical terms kept to a minimum
A contemporary approach, treating subjects of special interest to the church today
A friendly tone, appealing to the emotions and the spirit as well as the intellect
Frequent application to life
Resources for worship within each chapter
 

Bibliographies in each chapter that cross-reference subjects to a wide range of other systematic theologies.
