In case we have any question about the tone in which the psalmist is making the statements in verses 39-45, we find ourselves pointed in the right direction in the eighth and final stanza (vv. 46–51). Here we have his appeal, focused on the question: "How long, O LORD" (v. 46)? It is a common question of the saints, arising out of what seems to be a breaking of the covenant. In Revelation the saints ask God, "How long, Sovereign Lord, holy and true, until you judge the inhabitants of the earth and avenge our blood" (Rev. 6:10)? Believers ask this when they feel abandoned and when God does not seem to act. But the cry is not unbelief. On the contrary, it is the cry of faith, for it is to God, and it is looking for an answer.

What is most striking about the phrasing of the psalmist’s list of accusations is that God is held to be responsible. Notice the pronoun "you," meaning God. It is the subject of nearly every sentence in this section (eleven times in the New International Version). The only sentences that do not have God as their subject are in verse 41:

Psalm 89 has the distinction of being one of the greatest passages in the Bible dealing with the faithfulness of God. But it does it in two ways. The first half praises God for his faithfulness exuberantly and without any qualifications. It particularly praises him for his faithfulness in keeping his covenant with King David (2 Sam. 7). The latter half expresses the gap between the promise and reality.

Verses 19-29 are essentially a commentary on 2 Samuel 7. This stanza highlights six critical features of God's covenant with David, three of which we looked at yesterday, and the remaining three of which we take up today.

Having moved from heaven to earth and from nature to the specific event of the Jewish Exodus from Egypt, the writer now turns to the faithfulness of God to his people generally (vv. 14-18). At this point he brings in many other attributes of God which his people have experienced and for which they praise him. These attributes are added to faithfulness as basic to God's character and as a foundation for faith in his faithfulness. God has the power to be faithful, but does he want to be? Is God willing? These attributes assure us that the answer is "Yes."
