This is about God’s covenant with David,
2 Samuel 7:10 Moreover I will appoint a place for my people Israel, and will plant them, that they may dwell in a place of their own, and move no more; neither shall the children of wickedness afflict them any more, as beforetime,
The first term is that Jews would live in a place of peace and no one would afflict them again. Hence came the term “Pray for the peace of Jerusalem”, which was referring to David at that time. It is not fulfilled until Jesus Christ will come again and set up His Kingdom in Jerusalem.
2 Samuel 7: 12-14; cf Hebrews 1:5
David’s seed will build a temple for God. Dispensationalism shows that it was both Solomon and Jesus Christ who built the temple for God. Verse 14 has clearly separated the context to both Solomon and Jesus.
1 Samuel 8:4 Then all the elders of Israel gathered themselves together, and came to Samuel unto Ramah,
The theme is about the Kingdom because Jews rejected a Spiritual God as King and wanted a physical kingdom instead. A lot of physical kingdoms mentioned in the Old Testament are for Israel, not for us Christians. We Christians will inherit a spiritual kingdom instead.
Jews believe in physical salvation by the works of the law, and they think salvation by faith without works of the law is not valid. Nonetheless, we can look at David, who failed in his physical works. By Jewish law, he should lose his salvation. However, David managed to receive mercy and imputed righteousness from God.
2 Samuel 12:9,13 Wherefore hast thou despised the commandment of the Lord, to do evil in his sight? thou hast killed Uriah the Hittite with the sword, and hast taken his wife to be thy wife, and hast slain him with the sword of the children of Ammon. And David said unto Nathan, I have sinned against the Lord. And Nathan said unto David, The Lord also hath put away thy sin; thou shalt not die.
Psalm 51:1 Have mercy upon me, O God, according to thy lovingkindness: according unto the multitude of thy tender mercies blot out my transgressions.
David committed two severe sins, and he begged for mercy from God.
Romans 4:6 Even as David also describeth the blessedness of the man, unto whom God imputeth righteousness without works,
So Paul was able to reference this to argue for Christian doctrines and our spiritual dealings with God; that our salvation is justified by God’s grace through faith.
2 Samuel 24:18 And Gad came that day to David, and said unto him, Go up, rear an altar unto the Lord in the threshing floor of Araunah the Jebusite.
Even though God had mercy on David for his severe sins committed on adultery and murder, David was fully aware that the shedding of animal’s blood and sacrifices were still required. He recognized he needed to build an altar for burnt offerings and peace offerings.
Although we can see that God’s dealings with the people were predominantly physical and by law in the Old Testament, there were a few exceptions. For instance, Lot who committed incest relationships, and Samson who committed fornication, were still regarded as the heroes of faith in the eyes of God.
We need to avoid the doctrines of hyper dispensationalism and covenant theology, which do not believe in verse separation. A lot of them think that God’s grace is only applicable to us Christians in the New Testament, but we clearly see that God’s grace was also obvious in some of the cases in the Old Testament towards a few people.
2 Thessalonians 2:2: “That ye be not soon shaken in mind, or be troubled, neither by spirit, nor by word, nor by letter as from us, as that the day of Christ is at hand.”
2 Timothy 4:8: “Henceforth there is laid up for me a crown of righteousness, which the Lord, the righteous judge, shall give me at that day: and not to me only, but unto all them also that love his appearing.”
‘That day’ is known as the Judgment seat of Christ, when Christians will be raptured and face the Judgment of Jesus Christ.
