A summer of Sabbatical Study in 2015 allowed me to explore this vital question. I have put my findings on a separate website bringing together a number of articles on the theme of helping every Christian to take every opportunity to share their faith. Visit www.takingeveryopportunity.org
Taking Every Opportunity – Conversations about Jesus is the paper which sums up the conclusions of my Sabbatical Studies. Different aspects of the theme are then expanded in these other articles found on the website. http://pbthomas.com/takingeveryopportunity/taking-every-opportunity-conversations-about-jesus/
42 Great Outreach Ideas is a simple blog bringing together practical approaches to starting and encouraging conversations about Jesus. http://pbthomas.com/takingeveryopportunity/42-great-outreach-ideas/
Preaching the Gospel Necessarily Includes Words defends that understanding against the mistaken notion that we can somehow witness to Jesus by our actions and that talking about Jesus should only be a last resort. http://pbthomas.com/takingeveryopportunity/preaching-the-gospel-necessarily-includes-words/
Prepared to Answer explains a simple programme of sermons, workshops and other activities to help Christians prepare themselves to talk about Jesus.
Prepared to Answer Sermons links to the sermons in the series which were preached at North Springfield Baptist Church in the autumn of 2015. http://pbthomas.com/blog/?cat=47
Prepared To Give An Answer is the book I wrote in 2016 bringing together all these materials and other insights on talking about Jesus.
