A few weeks ago we saw from Romans 12:3-8 that one of the major New Testament pictures for the church is that of a body (see also 1 Corinthians 12).
Another image that is used frequently is that of a family (see for example Mark 3:34; 1 Timothy 3:15).
However, any mention of “family” need to be considered carefully. Krish Kandiah has a helpful article looking at various ways the church is pictured.
Take a look here, and see what you think of his conclusion.
