From G2842 (koinonia, 'fellowship/sharing'). Koinonikos describes one who is disposed toward sharing β generous, open-handed, communally minded. The adjectival form of the great NT word for Christian fellowship.
1 Timothy 6:18 commands the wealthy to 'be rich in good works, ready to distribute, willing to communicate (koinonikos).' The word captures the disposition of the generous heart β not merely giving when asked but actively looking for ways to share. True koinonia (fellowship) is not a spiritual feeling but a practical sharing of resources. Acts 2:44β45 describes the early church's radical koinonikos lifestyle: 'all things common... sold possessions... distributed to all as any had need.' The generous believer embodies the character of the God who gave His only Son β and continues giving through His people.
