Absolutely. I have been a Christian since the age of 6. Grew up in the Church of Christ until I was a teenager, then begain going to a Baptist church (girlfriend, later wife, went there). Was not close to God from about 16-28, then re-dedicated my life to Him, and now regret those years where I was not close, as I made so many mistakes with nobody to look to for guidance or help. I began reading the Bible again (though I'd read it before, I only had read it - I hadn't really READ it, if you know what I mean). Had a miscarriage, which is really what it took for God to grab ahold of my life and make me get it together. It's really unfortunate that that's what it took, especially for my wife, who had been a strong Christian all along, but God works in mysterious ways. I am now fully on track with a strong relationship with Jesus Christ.
One of my biggest pet peeves is when the gospel is diluted. Christianity is by its nature exclusive, b/c it preaches one way. When others claim there are other ways, it is really diluting the gospel, which is not our right, and not what the Bible says is correct.
I truly have a heart for the lost (whether they think they are or not), and desire to tell as many as possible. Other people choose to use life model as their witness, I choose to use words. At least when I stand before God, I can say that I was never silent about His word with others, and nobody will be able to look at me and say "Why didn't you tell me what you knew, so I could have it to?"
