What is the definition of fellowship in the Bible?

Biblical fellowship can be between two individuals. The best example of this is the fellowship that Jesus wants to have personally with each of us. Revelation 3:20 says, “Behold, I stand at the door and knock. If anyone hears My voice and opens the door, I will come in to him and dine with him, and he with Me.” This passage is written to the Church (the saved). Take note that Jesus is speaking and knocking and that He refers to the one on the other side of the door as “him,” singular. Jesus desires for each one of us to have and maintain intimate fellowship with Him through personal time in prayer and purposeful time in His Word.

Fellowship can also be corporate, like that of a church or small group. For instance, in Acts chapter 2, there is a day on which 3000 people got saved. Now you take 3000 people and put them all in Disneyland. Not all who are there have the same purpose for being there. The 3000 people of Acts chapter 2 were all at the same event, but there was a oneness that was there because of salvation in Jesus. Acts 2:42 says, “And they continued steadfastly in the apostles’ doctrine and fellowship, in the breaking of bread, and in prayers.” They experienced oneness in purpose and action, and they experienced fellowship with the Lord corporately. This kind of fellowship strengthens the bond we have in Christ and with each other as we encourage one another to be faithful in our walk with our Lord and Savior. 1 John 1:7 reminds us, “But if we walk in the light as He is in the light, we have fellowship with one another, and the blood of Jesus Christ His Son cleanses us from all sin.”
