TOPIC: David: The Giant Slayer (Mountain Of Fire and Miracle Ministries, MFM Devotional 27 February 2026)
BIBLE IN ONE YEAR: Deuteronomy 19, Deuteronomy 20, Deuteronomy 21, Galatians 3, Galatians 4.
FIRE SCRIPTURE: 1 Samuel 17:31-50 (KJV)
31 And when the words were heard which David spake, they rehearsed them before Saul: and he sent for him.
32 And David said to Saul, Let no man’s heart fail because of him; thy servant will go and fight with this Philistine.
33 And Saul said to David, Thou art not able to go against this Philistine to fight with him: for thou art but a youth, and he a man of war from his youth.
34 And David said unto Saul, Thy servant kept his father’s sheep, and there came a lion, and a bear, and took a lamb out of the flock:
35 And I went out after him, and smote him, and delivered it out of his mouth: and when he arose against me, I caught him by his beard, and smote him, and slew him.
36 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.
37 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.
38 And Saul armed David with his armour, and he put an helmet of brass upon his head; also he armed him with a coat of mail.
39 And David girded his sword upon his armour, and he assayed to go; for he had not proved it. And David said unto Saul, I cannot go with these; for I have not proved them. And David put them off him.
40 And he took his staff in his hand, and chose him five smooth stones out of the brook, and put them in a shepherd’s bag which he had, even in a scrip; and his sling was in his hand: and he drew near to the Philistine.
41 And the Philistine came on and drew near unto David; and the man that bare the shield went before him.
42 And when the Philistine looked about, and saw David, he disdained him: for he was but a youth, and ruddy, and of a fair countenance.
43 And the Philistine said unto David, Am I a dog, that thou comest to me with staves? And the Philistine cursed David by his gods.
44 And the Philistine said to David, Come to me, and I will give thy flesh unto the fowls of the air, and to the beasts of the field.
45 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.
46 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.
47 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.
48 And it came to pass, when the Philistine arose, and came, and drew nigh to meet David, that David hastened, and ran toward the army to meet the Philistine.
49 And David put his hand in his bag, and took thence a stone, and slang it, and smote the Philistine in his forehead, that the stone sunk into his forehead; and he fell upon his face to the earth.
50 So David prevailed over the Philistine with a sling and with a stone, and smote the Philistine, and slew him; but there was no sword in the hand of David.
MEMORY VERSE: So David prevailed over the Philistine with a sling and with a stone, and smote the Philistine, and slew him; but there was no sword in the hand of David. – 1 Samuel 17:50 (KJV)

MFM Devotional For Today 2026 MESSAGE:
The most popular story about David in the Bible is probably the one about his encounter with Goliath. The Philistine giant had been boasting against the Israelite army and nobody, including King Saul, could do anything. When Jesse sent David to the battlefield, he thought he was sending him to deliver food to his brothers but he really was launching him into destiny.

David heard the Philistine boast and he decided to take action despite his eldest brother’s rebuke. When David stood before Saul, he told him of how he had killed a lion and a bear that had come against a lamb in his flock. David was bold because he had tested God in the wilderness and he had an assurance. If God did not fail you in the wilderness, He definitely would not fail you on the battlefield.
Saul armed him with his armour but he couldn’t move so he went for the familiar sling and stones. The lesson here is profound. You do not use untested weapons on the battlefield. If you haven’t been grooming your spirit through exercises like prayer, fasting, Word study, you will not be able to stand on the day of battle. That is why Paul encourages believers to always put on the whole armour of God and stand (Ephesians 6:11-13).
More interesting is the dialogue between David and Goliath. It is important to confess your victory with your mouth, no matter the size of the enemy facing you. David told Goliath that he had come against him in the Name of the Lord, and that he would kill him. That was exactly what happened. God worked through those stones and silenced the wicked enemy.
Beloved, refuse to be bullied into silence; refuse to confess negatively. Rather, proclaim the Name of Jesus over every situation and watch your enemies be put to shame. If you are ever threatened by a wicked personality, do not cower in fear, reply them and return their threat in the Name of Jesus. The Lord will strengthen you to cut off the head of every Goliath that rises against you, in Jesus’ Name.
