Psalms 107:16

This description of prisoners and captives intimates that they are desolate and sorrowful. In the eastern prisons the captives were and are treated with much severity. Afflicting providences must be improved as humbling providences; and we lose the benefit, if our hearts are unhumbled and unbroken under them. This is a shadow of the sinner's deliverance from a far worse confinement. The awakened sinner discovers his guilt and misery. Having struggled in vain for deliverance, he finds there is no help for him but in the mercy and grace of God. His sin is forgiven by a merciful God, and his pardon is accompanied by deliverance from the power of sin and Satan, and by the sanctifying and comforting influences of God the Holy Spirit.

For he hath broken the gates of brass, and cut the bars of Zion in sunder. This verse belongs to that which precedes it, and Sums up the mercy experienced by captives. The Lord breaks the strongest gates and bars when the time comes to set free his prisoners: and spiritually the Lord Jesus has broken the most powerful of spiritual bonds and made us free indeed. Brass and iron are as tow before the flame of Jesus' love. The gates of hell shall not prevail against us, neither shall the bars of the grave detain us. Those of us who have experienced his redeeming power must and will praise the Lord for the wonders of his grace displayed on our behalf.
