I understand your concerns, OP, and in some cases you might be right.
However, I know with my physical disabilities CC fills a large void in my life. I do volunteer work in long term care for 6 hours a week, encouraging the disabled and elderly. I am leading a Bible study introducing non-Christians to Jesus. More than that is just too physically wearing for me.
So the other hours, I am happy to visit this and some other internet sites, and do ministry here. I pray for those with needs, I try and be a witness for Christ. I also try and encourage those who are suffering that God is with them.
The work of God needs to be done. But in my internet work, I have led people to Christ from Tibet, England and South Africa. I have helped those in my own country and the US. I have met Christians from around the world, who are engaged in internet ministry.
I truly believe that the spread of the gospel can be great through the internet and sites like CC. God will use Balaam's donkey to do his will, and he will certainly use a site like ChristianChat to accomplish his purposes.
I am glad you posted this. We do need to be reminded to be about God's business. I hope and pray that he who has ears to hear will hear and be inspired to serve Christ in whatever capacity he leads!
