My Servant David 
Part One
Go and tell my servant David, Thus saith the LORD 
(2 Samuel 7:5a)
Brothers and sisters in the Lord, this subject has been touched on in various writings in the past; how it is our own righteousness that delights the LORD. 
Also, the mystery of iniquity was a great puzzle; how people could hear the words of Truth and not react thereto, but carry on in the same old evil way. 
It would seem that the answer lies in the above passage of Scripture. Only when I willingly submit my soul to Him shall I be blessed with His promises. 
*A Psalm of David.* The LORD is my shepherd; I shall not want. He maketh me to lie down in green pastures: he leadeth me beside the still waters. He restoreth my soul: he leadeth me in the paths of righteousness for his name's sake. Yea, though I walk through the valley of the shadow of death, I will fear no evil: for thou art with me; thy rod and thy staff they comfort me. Thou preparest a table before me in the presence of mine enemies: thou anointest my head with oil; my cup runneth over. Surely goodness and mercy shall follow me all the days of my life: and I will dwell in the house of the LORD for ever. 
(Psalms 23:1-6)
David had been a shepherd boy, with long periods of solitude, looking at creation around him, realising that there was a God, that it was God of Israel (Elohim) and reacting to that realisation in a positive way. 
David humbled himself in the sight of the LORD and he was lifted up both spiritually and physically, but he never forgot who he was and who the LORD was. 
It was a Master/servant (willing slave) relationship. 
While still a shepherd lad his faith in God was such that he stood before a nine foot high enemy and killed him. 
Thy servant slew both the lion and the bear: and this uncircumcised Philistine shall be as one of them, seeing he hath defied the armies of the living God. David said moreover, The LORD that delivered me out of the paw of the lion, and out of the paw of the bear, he will deliver me out of the hand of this Philistine. And Saul said unto David, Go, and the LORD be with thee. 
(1 Samuel 17:36-37)
Then said David to the Philistine, Thou comest to me with a sword, and with a spear, and with a shield: but I come to thee in the name of the LORD of hosts, the God of the armies of Israel, whom thou hast defied. This day will the LORD deliver thee into mine hand; and I will smite thee, and take thine head from thee; and I will give the carcases of the host of the Philistines this day unto the fowls of the air, and to the wild beasts of the earth; that all the earth may know that there is a God in Israel. And all this assembly shall know that the LORD saveth not with sword and spear: for the battle is the LORD'S, and he will give you into our hands. 
(1 Samuel 17:45-47)
When he was king of all Israel, a worldly dictator, he brought the ark of the Covenant into the city of Zion dancing with all his might before the LORD, demonstrating before his subjects his relationship with God. 
We see that at times he consulted with and listened to God and at others worked through Nathan the prophet. 
The Philistines also came and spread themselves in the valley of Rephaim. And David enquired of the LORD, saying, Shall I go up to the Philistines? wilt thou deliver them into mine hand? And the LORD said unto David, Go up: for I will doubtless deliver the Philistines into thine hand. And David came to Baalperazim, and David smote them there, and said, The LORD hath broken forth upon mine enemies before me, as the breach of waters. Therefore he called the name of that place Baalperazim. And there they left their images, and David and his men burned them. And the Philistines came up yet again, and spread themselves in the valley of Rephaim. And when David enquired of the LORD, he said, Thou shalt not go up; but fetch a compass behind them, and come upon them over against the mulberry trees. And let it be, when thou hearest the sound of a going in the tops of the mulberry trees, that then thou shalt bestir thyself: for then shall the LORD go out before thee, to smite the host of the Philistines. And David did so, as the LORD had commanded him; and smote the Philistines from Geba until thou come to Gazer. 
(2 Samuel 5:18-25)
And it came to pass, when the king sat in his house, and the LORD had given him rest round about from all his enemies; That the king said unto Nathan the prophet, See now, I dwell in an house of cedar, but the ark of God dwelleth within curtains. And Nathan said to the king, Go, do all that is in thine heart; for the LORD is with thee. And it came to pass that night, that the word of the LORD came unto Nathan, saying, Go and tell my servant David, Thus saith the LORD, Shalt thou build me an house for me to dwell in? Whereas I have not dwelt in any house since the time that I brought up the children of Israel out of Egypt, even to this day, but have walked in a tent and in a tabernacle. In all the places wherein I have walked with all the children of Israel spake I a word with any of the tribes of Israel, whom I commanded to feed my people Israel, saying, Why build ye not me an house of cedar? Now therefore so shalt thou say unto my servant David, Thus saith the LORD of hosts, I took thee from the sheepcote, from following the sheep, to be ruler over my people, over Israel: And I was with thee whithersoever thou wentest, and have cut off all thine enemies out of thy sight, and have made thee a great name, like unto the name of the great men that are in the earth. 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, And as since the time that I commanded judges to be over my people Israel, and have caused thee to rest from all thine enemies. Also the LORD telleth thee that he will make thee an house. And when thy days be fulfilled, and thou shalt sleep with thy fathers, I will set up thy seed after thee, which shall proceed out of thy bowels, and I will establish his kingdom. He shall build an house for my name, and I will stablish the throne of his kingdom for ever. I will be his father, and he shall be my son. If he commit iniquity, I will chasten him with the rod of men, and with the stripes of the children of men: But my mercy shall not depart away from him, as I took it from Saul, whom I put away before thee. And thine house and thy kingdom shall be established for ever before thee: thy throne shall be established for ever. According to all these words, and according to all this vision, so did Nathan speak unto David. 
(2 Samuel 7:1-17)
However, we see that this great king never forgot who it was who blessed and rewarded him. 
Then went king David in, and sat before the LORD, and he said, Who am I, O Lord GOD? and what is my house, that thou hast brought me hitherto? And this was yet a small thing in thy sight, O Lord GOD; but thou hast spoken also of thy servant's house for a great while to come. And is this the manner of man, O Lord GOD? And what can David say more unto thee? for thou, Lord GOD, knowest thy servant. For thy word's sake, and according to thine own heart, hast thou done all these great things, to make thy servant know them. Wherefore thou art great, O LORD God: for there is none like thee, neither is there any God beside thee, according to all that we have heard with our ears. And what one nation in the earth is like thy people, even like Israel, whom God went to redeem for a people to himself, and to make him a name, and to do for you great things and terrible, for thy land, before thy people, which thou redeemedst to thee from Egypt, from the nations and their gods? For thou hast confirmed to thyself thy people Israel to be a people unto thee for ever: and thou, LORD, art become their God. And now, O LORD God, the word that thou hast spoken concerning thy servant, and concerning his house, establish it for ever, and do as thou hast said. And let thy name be magnified for ever, saying, The LORD of hosts is the God over Israel: and let the house of thy servant David be established before thee. For thou, O LORD of hosts, God of Israel, hast revealed to thy servant, saying, I will build thee an house: therefore hath thy servant found in his heart to pray this prayer unto thee. And now, O Lord GOD, thou art that God, and thy words be true, and thou hast promised this goodness unto thy servant: Therefore now let it please thee to bless the house of thy servant, that it may continue for ever before thee: for thou, O Lord GOD, hast spoken it: and with thy blessing let the house of thy servant be blessed for ever. 
(2 Samuel 7:18-29)
And that Person who was described in the above prophecy said: 
These things have I spoken unto you, that my joy might remain in you, and that your joy might be full. This is my commandment, That ye love one another, as I have loved you. Greater love hath no man than this, that a man lay down his life for his friends. Ye are my friends, if ye do whatsoever I command you. Henceforth I call you not servants; for the servant knoweth not what his lord doeth: but I have called you friends; for all things that I have heard of my Father I have made known unto you. Ye have not chosen me, but I have chosen you, and ordained you, that ye should go and bring forth fruit, and that your fruit should remain: that whatsoever ye shall ask of the Father in my name, he may give it you. 
(John 15:11-16)
Oh what joy it is to be called a friend of the Most High. 
Sanctify yourselves therefore, and be ye holy: for I am the LORD your God. And ye shall keep my statutes, and do them: I am the LORD which sanctify you. 
(Leviticus 20:7-8)
