While God's goodness might be hidden like a treasure, it's also actively worked out and displayed for all to see. How does that work?
The verse continues by stating that God's goodness is "worked for those who take refuge in you, in the sight of the children of mankind." This reveals a dual aspect: the intimate, reserved goodness for the faithful, and its public manifestation. God doesn't just hoard His goodness; He actively performs and displays it. This 'working' is for those who actively place their trust in Him. Crucially, this goodness is made evident "in the sight of the children of mankind." Even when the world doesn't understand or acknowledge it, God's actions on behalf of His trusting people are meant to be visible, serving as a testament to His power, faithfulness, and the reality of His care.
