We know that David says much to the Lord during his lifetime on earth. He sings His praises; he prays for deliverance; he begs for forgiveness.
David knows God’s greatness firsthand. He has seen it. “Because of Your promise, and according to Your own heart, You have brought out this greatness, to make Your servant know it.” (2 Samuel 7: 21)
God reveals Himself to David.
“Therefore You are great, O Lord God. For there is none like You, and there is no God besides You, according to all that we have heard with our ears.” (2 Samuel 7: 22)
David anticipates that he will be God’s servant forever, not only for his lifetime. He knows the “house of [God’s] servant David will be established before” Him forever.
David finds the courage to pray to the Lord a blessing on his house forever. He says, “You have spoken also of Your servant’s house for a great while to come, and this is instruction for mankind, O Lord God!” (2 Samuel 7: 19)
David tells us that his house is blessed. He is God’s servant. This instruction is for mankind. From David’s throne comes a savior, who is Christ the Lord.
“And Your Name will be magnified forever, saying, ‘The Lord of hosts is God over Israel,’ and the house of Your servant David will be established before You.” (2 Samuel 7: 26)
God says to David, “I will build you a house.” (2 Samuel 7: 27) God blesses this house; and God’s blessing is a never-ending one.
“Surely goodness and mercy shall follow me all the days of my life, and I shall dwell in the house of the Lord forever.” (Psalm 23: 6)
