Anna, I’m an idealist at heart, and it sounds like you are too. As an idealist words like strategy and training still make me cringe when it comes to dealing with people. But knowing how to help others come to faith in Jesus is not something that comes naturally to a lot of people, even if they have a lot of zeal or enthusiasm or conviction.
So,
a) You can’t be a Christian without understanding the gospel story! Therefore, a Christian has sufficient to say already.
You’d be surprised how many people trust in God but have no idea how to explain to someone else what they need to do to be saved.
b) As far as I can tell, the Christians in the Bible weren’t too fussed about this [objection answering].
I don’t think this is true. I’m sure Paul did lots of objection answering when he was “reasoning daily in the hall of Tyrannus. This continued for two years” (Acts 19:9-10) and when “he powerfully refuted the Jews in public, showing by the Scriptures that the Christ was Jesus.” (Acts 18:28)
And I think the famous 1 Peter 3:15 is relevant: “in your hearts honor Christ the Lord as holy, always being prepared to make a defense to anyone who asks you for a reason for the hope that is in you”
I believe cause it’s true and I’m really excited is not a reason - we need to know why we believe. If we don’t understand the objections of others our faith will remain shallow.
c) A Christian should naturally want to learn more about their God and Saviour - but again, not as an evangelistic strategy.
Knowing the Bible well is extremely important for evangelism - you can’t separate them and say “you shouldn’t learn about the Bible for the sake of evangelism”.
d) Knowing how to broach the subject with others? It seems you couldn’t stop Christians blabbing about it in Acts! Again, I think this has less to do with ‘training’ and a heap more to do with ‘conviction’! I think in this area particularly, strategies are foolish. If a Christian can’t raise the issue with someone there is a massive problem. Basically: Open your mouth, and say, “Hey, I’d like to tell you some great news. It’s about Jesus”, and take it from there. The reason I don’t do it much is because I’m scared and more interested in my own comfort than in others’ salvation - it’s not because I’m incompetent. I imagine it’s the same for others. Saying we need training rather than regeneration is a major cop-out!
If “Hey, I’d like to tell you some great news. It’s about Jesus” works for you, that’s great, and I know it does for some. But others will find this doesn’t lead to worthwhile conversations and need advice about how else they can do it. Your typical extrovert may not need this advice.
Regeneration does not lead to good conversation skills!
