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.
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.
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.
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.
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.
