J. I. Packer, Evangelism and the Sovereignty of God, pp. 41, 50
How then should evangelism be defined? The N. T. answer is very simple. According to the N. T., evangelism is just preaching the gospel, the evangel. Evangelizing, therefore is not simply a matter of teaching, and instructing, and imparting information to the mind. There is more to it than that. Evangelism includes the endeavor to elicit a response to the truth taught. It is communication with a view to conversion. It is a matter, not merely of informing, but also of inviting.
