Psalm 139:23

This verse is a bold prayer inviting God to examine the psalmist's heart and test his thoughts. Having spent the whole psalm marveling that God already knows him completely, the psalmist now welcomes that searching gaze rather than hiding from it. "Search me" and "try me" echo the psalm's opening, where God had already searched him -- but now the psalmist actively asks for it.

The request reaches to the inner life: the "heart" as the center of will and affection, and the "thoughts" as the stirrings of the mind. The word "try" carries the image of testing metal in fire to reveal what is pure and what is dross. This is no casual prayer; it is an act of trust that invites God to expose anything hidden, even what the psalmist himself cannot see. Such openness is only possible toward a God who is loving as well as all-knowing. The verse models the courage of honest self-examination before God -- not anxiously, but trusting that the One who searches us does so to lead us, as the next verse shows, into the way everlasting. It is the prayer of a heart that wants nothing between itself and God.
