Acts 11:25-26
25 Then Barnabas went to Tarsus to look for Saul, 26 and when he found him, he brought him to Antioch. So for a whole year Barnabas and Saul met with the church and taught great numbers of people. The disciples were called Christians first at Antioch.
Church is good, but there will always be some weeds among the wheat. A majority of times its selfishness that causes people to forsake meeting for corporate worship and fellowship. Sometimes they don't even realize they are the dandelion instead of the wheat!
