By 2030, Baby Boomers are expected to pass nearly $68 trillion in assets to their children, primarily millennials. This has raised concerns about the impact of declining church giving as Boomers pass away. To address this, Christian Boomers can leave a legacy of generosity by engaging with their family, planning their estates to include charitable giving, and educating and encouraging their heirs. Estate planning can include strategies for supporting churches, ministries, or missionaries, and ethical wills can capture life stories, religious values, ethics, and beliefs to pass on to future generations. Financial literacy should also be a focus to ensure heirs are prepared to handle the wealth they receive, promoting stewardship and generosity.
