Psalms 102:1
1Hear my prayer, LORD! Let my cry come to you.
The title names one afflicted who pours out complaint before the LORD. Wesley: a prayer for true Israelites on behalf of the church, near the end of captivity.
The psalmist moves from distress to petition. The cry is to be uttered; God invites the overwhelmed to speak. Grace stirs prayer; the afflicted must still cry.
Calvin: this earnestness shows the words were not for the careless. The captive Jews testify severe distress and an ardent desire for alleviation. The Holy Spirit stirs prayer for the common welfare of the Church; scarcely one in a hundred is affected as he ought by the Church's calamities.
The cry is Spirit-taught liturgy for a people, not a light mouth-habit. Heart and tongue help each other when grief shuts us up.
