In This We Believe, a statement of belief of our church body, you will find this confession: “We believe that people cannot produce this justifying faith, or trust, in their own hearts, because ‘the man without the Spirit does not accept the things that come from the Spirit of God, for they are foolishness to him’ (1 Corinthians 2:14). In fact, ‘the sinful mind is hostile to God’ (Romans 8:7). It is the Holy Spirit who gives people faith to recognize that ‘Jesus is Lord’ (1 Corinthians 12:3). The Holy Spirit works this faith by means of the gospel (Romans 10:17). We believe, therefore, that a person’s conversion is entirely the work of God’s grace. Rejection of the gospel is, however, entirely the unbeliever’s own fault (Matthew 23:37).”
Decision theology is not a teaching of the Bible.
