In general, fellowship is a close association, companionship, or friendship with others sharing mutual interests.
In a spiritual sense, fellowship can exist in two forms:
One is fellowship with God. God desires and longs for this fellowship.
The other is fellowship with others who share a common faith. God desires his followers to enjoy this type of fellowship, as well.
A lifelong student of the Bible, Peter DeHaan, PhD, wrote the 700-page website ABibleADay.com to encourage people to explore the Bible. His main blog and numerous books urge Christians to push past the status quo and reconsider how they practice their faith in every area of their lives.
