Typically, we prefer to be included, particularly in groups that make us feel special—in an inner ring, an exclusive club, an elite school, or even a street gang. The group might make us feel good or more secure about ourselves, but this implies exclusivity, treating those outside as inferior.
Christians don’t need to yearn to be included in earthly elite groups. In the days of the Old Testament, only the top Priest could be with God for just one day a year. Everyone else was excluded. But because of Christ experiencing the ultimate exclusion when He was forsaken by God the Father (Mark 15:34), we can be included in the family of God and never be forsaken by Him. We can be with God every day! With that, we clearly don’t need to be included in any worldly elite groups to feel good and secure.
Having said that, Christians should be with other Christians regularly (Hebrews 10:25). Why?
A Christian community’s main attribute is not just listening to people explain the Bible, but rather gathering in fellowship. It is where Christians help each other grow and support one another, particularly in difficult times. Oftentimes we are blind to our biggest flaws, but in community, Christians can lovingly and honestly confront and even challenge each other, so as to spur one another on toward love and good deeds (Hebrews 10:24-25).
But the Christian community is not a community that excludes others. The main goals of this group include welcoming and helping outsiders, and reaching out and serving even those who despise them.
Remember God loves us. Though we obviously don’t need to yearn to be members of worldly exclusive groups, we should be in a community of Christians, a group that not only helps its members, but welcomes and serves outsiders also.
Summarized from a Tim Keller sermon
话虽如此，基督徒却不应该停止聚会 （希伯来书10:25）。 这是为什么呢？
基督教群体的主要特征，不是听人讲解圣经，而是在一起团契。在那里, 基督徒互相帮助成长，互相支持托住, 特别是在困难的时期。我们常常看不到自己最大的缺点，但在基督徒群体中，基督徒可用爱心坦诚地彼此面对，甚至彼此挑战，彼此促进相爱和善行（希伯来书10：24-25）。
记住上帝爱我们。虽然我们不需盼望成为世俗杰出团体的成员，但我们应该属于基督徒群体的一分子, 一个不只是帮助自己, 更是欢迎和服侍外来者的群体。
