For many of us, evangelistic classes on how to evangelise fill us with guilt. We are even tempted to say
"Hey let's leave that to those gifted in evangelism". How is it possible then to have guilt free evangelism?
Simply by have a changed life, a transformed life where you are being made into the image of Christ.
The Scriptures actually teach this. All of 1 Peter talks about your identity in Christ and having different attitudes and behaviour to the world around. Being different to our culture. This is seen in the submit to those in Authority, slaves submit to your masters ( a principle applied today in our workforce ), wives submit to your husbands, husbands care and nurture your wives. Then some radical attitudes in 3:8-12. "finally all of you ( no one is left out here ) live in harmony with one another, be sympathetic, love the brethren, be humble"
And even the most famous passage of all that speaks of apologetics, giving a defense for your faith in 1 Peter 3:15f is predicated upon living a changed life so that when people ask of you Why you live this way you have an opportunity to answer them with the truth of the Gospel.
Josh McDowell understands this well. He was asked in an interview why young people still flock to hear him, and it was clear that it was because it is evident that he really cares for them.
1 Peter tells us to understand who we are in Christ and to display changed attitudes and work on our relationships within the Church. When we change people will ask us What has happened.
Now that's provoking isn't it?
