In the New Testament, Jesus Christ arms his disciples with treading power and the ability to bind and loose in the spirit realm to defeat the enemy. In what ways is the spiritual authority different from the Old Testament when David takes down Goliath in the name of the Lord, the God of Israel with a sling shot and a rock? I’ve been contemplating the difference.
Matthew 16:19 (KJV) And I will give unto thee the keys of the kingdom of heaven: and whatsoever thou shalt bind on earth shall be bound in heaven: and whatsoever thou shalt loose on earth shall be loosed in heaven.
Luke 10:19 (KJV)Behold, I give unto you power to tread on serpents and scorpions, and over all the power of the enemy: and nothing shall by any means hurt you. 20 Notwithstanding in this rejoice not, that the spirits are subject unto you; but rather rejoice, because your names are written in heaven.
21 In that hour Jesus rejoiced in spirit, and said, I thank thee, O Father, Lord of heaven and earth, that thou hast hid these things from the wise and prudent, and hast revealed them unto babes: even so, Father; for so it seemed good in thy sight.
Clearly David was able to take down Goliath with his faith in God and knowing his opponent had a weakness, he was not circumcised.
1 Samuel 17:26 (KJV) And David spake to the men that stood by him, saying, What shall be done to the man that killeth this Philistine, and taketh away the reproach from Israel? for who is this uncircumcised Philistine, that he should defy the armies of the living God?
In my mind, David saw that Goliath was not in obedience to God and he saw this as a weakness attached to Goliath’s forehead. David had faith that God would be on his side and had an intimate relationship with the Lord and a past history of God delivering him from difficult situations. I believe it was the difficult trials that gave this youth the faith and trust in god that he would put Goliath into the palm of his hand.
1 Samuel 17:37 (KJV) 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.
David verbally proclaims how he will take down Goliath. You see the power of verbal declaration in Proverbs 18:21.
Proverbs 18:21 (KJV) Death and life are in the power of the tongue: and they that love it shall eat the fruit thereof.
1 Samuel 17:45-50 (KJV) 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.
Jesus told his disciples that he has given them power to bind and loose and to tread in the spirit realm. Jesus is at the right hand of God and intercedes for us when we pray. I think the difference between the Old Testament and the New Testament is that the sling shot and rock are no longer required?
