How can you tell those who don't believe in Christ from those who do? It is not feeding the homeless, or taking care of widows, it isn't visiting the nursing homes or cleaning litter from the streets. Today there is a huge appeal for "deeds instead of creeds." The distinctive between the non-believer and the believer is the church. When you go to the church on Sunday and partake in the ordinances of both baptism and the Lord's supper then you can actually see the difference. Those who believe do all to the glory of Christ but a man who isn't in Christ will take glory for himself.
