The "Generosity Discipleship" eBook by Church Growth Services emphasizes that while churches often focus on discipleship areas like prayer and relationships, they frequently neglect teaching generosity. This oversight contributes to financial struggles, with 59% of churches experiencing declining or stagnant giving. The eBook underscores the importance of integrating generosity into discipleship, noting that the Bible contains over 2,300 verses on money and possessions, and 17 of Jesus' 38 parables address financial issues, highlighting the need for churches to develop comprehensive stewardship strategies.
