Is Dave against spontaneous or confrontational evangelism? Of course not, as long as the one proclaiming the gospel truly loves and cares for the other person/people. While the gospel will be a stumbling block and divisive, that doesn’t mean that the way we interact with people needs to be a stumbling block or divisive.
As Dave says:
The greatest danger of confrontational evangelism is that along with toughening our hides we harden our hearts. I urge all of us who share Jesus’ love with others to let our Christ-like actions speak as loud as our words. You lose nothing by protecting the dignity of non-believers. In fact, you may even gain a friend — and ultimately a brother or sister in Christ.
So, when you approach someone with the gospel, approach with the love of Christ, not like a charging rhino.
