Saving money and letting it compound over time really works. It was such a small amount that my husband and I ignored it and just let it grow. And the Lord blessed that decision in his abundance. What delights me even more is that God allowed me to contribute so fully, while staying at home, raising children and writing. While Christ was clear that our trust and sense of security shouldn't lie in our riches but in God, it is also a biblical principle to work diligently and plan for the future.
Ants never give up.
They plan for winter all summer. They plan for summer all winter. And while they gather food for winter, they gather all they can. Another reason to save is that our life expectancy is getting longer. Your retirement may last 20-30 years.
