It is written by The Holy Spirit in 1 Samuel chapter 16:
1 Now the LORD said to Samuel, “How long will you mourn for Saul, seeing I have rejected him from reigning over Israel? Fill your horn with oil, and go; I am sending you to Jesse the Bethlehemite. For I have provided Myself a king among his sons.”
2 And Samuel said, “How can I go? If Saul hears it, he will kill me.”
But the LORD said, “Take a heifer with you, and say, ‘I have come to sacrifice to the LORD.’ 3 Then invite Jesse to the sacrifice, and I will show you what you shall do; you shall anoint for Me the one I name to you.”
4 So Samuel did what the LORD said, and went to Bethlehem. And the elders of the town trembled at his coming, and said, “Do you come peaceably?”
5 And he said, “Peaceably; I have come to sacrifice to the LORD. Sanctify yourselves, and come with me to the sacrifice.” Then he consecrated Jesse and his sons, and invited them to the sacrifice.
6 So it was, when they came, that he looked at Eliab and said, “Surely the LORD’s anointed is before Him!”
7 But the LORD said to Samuel, “Do not look at his appearance or at his physical stature, because I have refused him. For the LORD does not see as man sees; for man looks at the outward appearance, but the LORD looks at the heart.”
FATHER makes it quite clear that HE looks at our heart, not our external appearance or age. You and I are qualified for the “anointing” based on the condition of our hearts thus we do not need to be concerned about what others think or say concerning their observations and opinions. We must not listen to the world in determining what we are able to do for THE LORD.
10 Thus Jesse made seven of his sons pass before Samuel. And Samuel said to Jesse, “The LORD has not chosen these.” 11 And Samuel said to Jesse, “Are all the young men here?” Then he said, “There remains yet the youngest, and there he is, keeping the sheep.”
And Samuel said to Jesse, “Send and bring him. For we will not sit down till he comes here.” 12 So he sent and brought him in. Now he was ruddy, with bright eyes, and good-looking. And the LORD said, “Arise, anoint him; for this is the one!” 13 Then Samuel took the horn of oil and anointed him in the midst of his brothers; and the Spirit of the LORD came upon David from that day forward. So Samuel arose and went to Ramah.
We are not told how old David was when Samuel anointed him but his family did not consider him to be mature enough to be considered by the prophet. People always underestimate FATHER’S Plan.
In chapter 17, David asks the question:
26 Then David spoke to the men who stood by him, saying, “What shall be done for the man who kills this Philistine and takes away the reproach from Israel? For who is this uncircumcised Philistine, that he should defy the armies of the living God?”
If you have no covenant with Our Heavenly Father, you are uncircumcised. David understood covenant and stood upon that covenant when confronted with a “giant”. David then provides us with the state of his heart:
34 But David said to Saul, “Your servant used to keep his father’s sheep, and when a lion or a bear came and took a lamb out of the flock, 35 I went out after it and struck it, and delivered the lamb from its mouth; and when it arose against me, I caught it by its beard, and struck and killed it. 36 Your servant has killed both lion and bear; and this uncircumcised Philistine will be like one of them, seeing he has defied the armies of the living God.” 37 Moreover David said, “The LORD, who delivered me from the paw of the lion and from the paw of the bear, He will deliver me from the hand of this Philistine.”
David stated that he was no longer keeping sheep and had relied on FATHER to deliver him from both a bear and a lion. FATHER had been preparing David to conquer Goliath just as FATHER has been preparing you and me to be delivered from our “Goliaths”.
What is your Goliath? Is it sickness, disease, age, your job, your relationship with another? No matter what overwhelming issue is facing you, FATHER has provided HIS anointing for you to overcome your situation. David had spent years practicing with a slingshot. He had also spent years practicing with a stringed instrument. Both served him well when it came time to deal with overwhelming issues.
FATHER has your and my provision awaiting our request for activation and implementation. We are meant to be overcomers, not just onlookers. It is time to slay our “Goliaths” once and for all.
