Just as a child growing up will require the care of a family, so a new Christian will need to establish relationships with other members of the family of God.
A plant must be surrounded by good soil in order for it to receive nourishment and properly grow. If the soil is deficient the plant will wither; if it is rich in nutrients, the plant can then thrive.
A healthy Christian will desire to fellowship with other believers who have genuinely made Christ the Lord of their lives.
Who should I fellowship with?
The only way someone can see the personality of Jesus Christ, outside of the Bible, is through His people; through Christians.
As you develop relationships with other genuine Christians, you are able to see more clearly the character of Jesus Christ.
“Now, therefore, you are no longer strangers and foreigners, but fellow citizens with the saints and members of the household of God” (Ephesians 2:19)
Who should I NOT fellowship with?
The Bible says: “Do not be unequally yoked together with unbelievers. For what fellowship has righteousness with lawlessness? (2 Corinthians 6:14)
Have “close” contact with Christians to learn about the Christ.
Have “cautious” contact with non-Christians to share Christ.
