What is the hidden man of the heart in 1 Peter 3:4?
The hidden man of the heart is the born-again spirit within a believing woman, an incorruptible inner person. It is the ornament of a meek and quiet spirit, not outward adornment like braided hair, gold, or apparel. This inner adorning is precious in God's sight and wins an unbelieving husband without preaching or nagging.
Les teaches from 1 Peter 3 that believing wives are to be in subjection to their husbands so that an unbelieving husband may be won without a word—not by preaching, nagging, or dragging him to church—but by the wife's chaste manner of living coupled with fear. The hidden man of the heart is the born-again spirit within that believing woman, an incorruptible inner adorning rather than outward braiding, gold, or apparel. It is the ornament of a meek and quiet spirit, which in God's sight is of great price. Les explains this as a generic term for the believing woman's inner life, and she should live an exemplary Christian life before her husband.
But let it be the hidden man of the heart, in that which is not corruptible, even the ornament of a meek and quiet spirit, which is in the sight of God of great price.
