The greatest challenge is not technology or cost. The greatest challenge is the attitude of churches and Christians today. It is proper church-speak to talk about winning the lost, but the inactivity and lack of any outreach speaks the truth. The church really doesn't want to reach people for Christ.
I would like to issue a challenge those Christians who care about reaching a lost world with the gospel to go where most churches don't dare to go, and that is use the social media most of us already use, to reach others for Christ. Lets change this trend.
