Right on. You have no idea how many times I've heard this excuse in the Sunday School class I teach. Or it goes something like this..."If I live a good life, they will notice and want to come to Christ." UH...no. It doesn't work that way.
What I see today is a complete lack of understanding of what the gospel is and how powerful it is. Is our testimony, no matter how wonderful it is, the gospel? Don't think so....
My favorite is, "Friend, is there something missing in your life?"
I used to get that one a lot before I was a Christian. I just used to say "No, actually, my life is pretty sweet, but thanks for asking". I still hear that one every now and then.
I heard a preacher yesterday say "God loves you so much that if He had a wallet, your picture would be in it."
It should be more like, "If God had a Post Office, your picture would be on the wall".
The problem with the "If I can just live a good enough life to convince my neighbor..." school of evangelism is two-fold. The first is that, if our point is to live such a good life that we convince them, then we're not sharing the Gospel with them, we're just showing them what a swell guy we are because we keep the law.
If somebody does that, then they might as well go all the way and have a t-shirt made up that says "God, I thank thee, that I am not as other men are, extortioners, unjust, adulterers, or even as this publican. I fast twice in the week, I give tithes of all that I possess" and wear it around town.
The second problem is that, not only are they promoting their own goodness in following the law, they're also giving them the false idea that we are made righteous by our works. Instead of showing them how good we are (and we should also remember that, at our best, our works are still filthy rags before a Holy and Righteous God), we need to be explaining to them that we are not good and, while we're capable of doing things that are superficially good on occasion, we're sinful wretches before God and are incapable of pleasing Him by our works or our terrible attempts to keep the law and
that's why we need a Savior in the first place.
It's far better that I offend someone for a moment than that they burn in Hell for an eternity.
I enjoy your posts, by the way. Keep up the good work.
