Mutual Care – The church supported Paul while he was on the mission field. Those who truly care, care for the needs of others. This is the true spirit of Christ
Galatians 6:2 Bear ye one another's burdens, and so fulfil the law of Christ.
Mutual Prayer – Sometimes we can’t physically bear the burden of others, but we can pray for them. Paul reminds the Philippians that he prayed for them constantly. Believers ought to pray for one-another because there is power in prayer.
Mutual Love – Here‘s the true key to successful fellowship---genuine Christian love. It always shows itself when interacting with others. It‘s a mark of true salvation. True love promotes forgiveness, peace, joy, kindness, tenderness, meekness, blessing and acceptance.
1 John 3:18 My little children, let us not love in word, neither in tongue; but in deed and in truth.
Believers become mature Christians as they love, care, and pray for others. I call that sweet fellowship.
