Trust in the Lord with all thine heart; and lean not unto thine own understanding.

This line is a well-known biblical exhortation urging reliance on God rather than personal judgment. Although it may appear in devotional compilations associated with C. E. Cowman, it is primarily recognized as a scripture quotation rather than an original authored saying.

It encourages wholehearted dependence on God and cautions against treating one’s own reasoning as the ultimate guide, especially when making decisions or facing uncertainty.

Trust in the LORD with all your heart; and lean not on your own understanding.
