Without seeing the whole video, its rather impossible to see what was going on before, and how the whole situation developed, I wasn't even sure at first who was saying what. But what happened is the sort of outcome seem to indicate one is not doing it right.
So, when Jesus said things that people did not like, and they reacted in a bad way, was Jesus not doing it right? -Of course, He was.
The Gospel is offensive to the lost. Especially when we do as Jesus did and show people their evil deeds so that they will turn from them.
Sadly, too many Christians will criticise those who do go out and confront the lost while they themselves stay quiet.
Apologetics is about helping people with their misunderstandings about Christianity. Eristics is just arguing for the sake of arguing, seeking to win an argument. And devoid of christian love, it won't matter how good one's arguments are.
Sometimes we can make the very best argument for the existence of God and the Cross, but no matter how good the argument, a person’s heart may still remain hard. Yet you never know, they might go away and think about it.
I’ve had several debates with hard-core atheists, and at the end I often shake their hand and say, ‘Thanks for the discussion. You really pushed me, but I think you’ll agree I gave some solid answers.’ Most of the time, they smile, agree, and leave on good terms. When they acknowledge that I gave good answers, I believe a small pinprick has been made in their misunderstanding.
Charles Spurgeon understood that we are to do all we can to save the lost, and sometimes that may mean debating them when it seems like a lost cause. He said,
“If sinners be damned, at least let them leap to hell over our dead bodies.
And if they perish, let them perish with our arms wrapped about their knees,
imploring them to stay.
If hell must be filled, let it be filled in the teeth of our exertions, and let not one go unwarned and unprayed for.”
We need to do our best to reach these people. But remember, it’s not apologetics that changes a heart of stone into a heart of flesh. It’s the Gospel. Apologetics is useful, but only the Gospel transforms the heart.
