It’s really that simple. God intends for His people to agree with David’s prayer in 1 Chronicles 17:16-27. It’s the same with Paul’s prayers in the NT. Here are a few angles for preaching these Old and New Testament prayers.
First, theology about God, humankind, and redemption are to be believed. In 1 Chronicles 17:16-19 the sovereignty of God in choosing David results in David’s humility: “…Who am I, O Lord God…that you have brought me thus far?” (v. 16).
In v. 27 God is acknowledged as the Source of blessing.
Or, how about the theology in v. 20 “There is none like you, O Lord, and there is no God besides you…”
Second, what David wants for God is what we want for God too. Often the Church can pray the same requests as David (and Paul if you happen to be preaching in an epistle). We want God’s name to “be established and magnified forever” (v. 24).
Third and maybe most important for the Church is asking and answering the question, “Does God answer David’s prayer (or Paul’s prayer) and if so why?” God answers David’s prayer as long as David and God’s people fulfill the conditions of the covenant.
Of course, we know the rest of the Story: David and Solomon can’t keep the spiritual momentum going and the kingdom dissolves. Thankfully, we also know the rest of the rest of the Story: one greater than Solomon (cf. Matt. 12:42) arrives, perfectly keeps faith and through death, resurrection, ascension, and dispatching the Spirit becomes our Eternal King who secures the blessing of God for all who believe.
The prayers of David and Paul too, for that matter, are answered as Believers enjoy their privileged position in Christ.
I hope you’ll consider preaching these prayers of David so God can continue to receive glory in the church and in Christ Jesus (Ephesians 3:21).
