Read on to learn how to exercise the spiritual authority God has clothed you with!

Spiritual Authority of a Shepherd Boy

David was a young shepherd boy, the son of Jesse. He had three brothers who had gone to war alongside King Saul against the Philistines.

Goliath was their champion.

He was a giant who would come out each day and taunt the Israelites, including David’s brothers. He would challenge them to send someone to fight him. But not only would no one step up to battle this giant, they fled.

David’s father Jesse asked his young son to bring some food to his brothers on the front lines.

So David left his sheep in Bethlehem in the care of a shepherd and took off to the Valley of Elah to bring the grain and bread to his brothers.

David Meets Goliath

David arrives and he hears Goliath taunting the Israelites. So he asks what will be done for the man who can defeat Goliath.

He is told the King will give him great wealth, his daughter in marriage and his family will be tax exempt.

David apparently thinks this is worth the battle, so he tells King Saul that he will fight this giant.

Saul essentially laughs him off because he is just a child.

But David was not about to be laughed off. He basically reads Saul his resume and tells him of the time he killed a lion and a bear to protect the sheep.

He says this “uncircumcised Philistine” is just like a wild animal and that the same God who helped him defeat the lion and bear will allow him to defeat Goliath.

David did not put his faith in his own abilities when he told Saul about his conquests. He knew he had spiritual authority given by God and this enemy was no match for the God of Israel.

So Saul agrees and then proceeds to dress David in his own armor.

Saul’s Armor

Now it’s important to note that King Saul was a VERY tall man and David was a teenage boy. So his armor was not ideal for David. 

1 Samuel 17:39 says:

David buckled his sword on his armor and tried to walk, but he wasn’t used to such equipment. David said to Sha’ul, “I can’t move wearing these things, because I’m not used to them.” So David took them off.


Saul’s armor would not work for David because it was too big.

It was not meant for David, it was meant for Saul.

David tried to make it work because well…Saul was the king! But spiritual authority doesn’t come by forcing someone else’s armor to fit you in battle!

All David wanted or needed was the 5 smooth stones he picked up off the ground, his slingshot, and the God of Israel.

David took out Goliath with one shot and cut off his head with his Goliath’s own sword.

David didn’t need Saul’s armor. He only needed to put on the full armor of God, the Holy One of Israel.

His armor was his faith in God!

Put on the Full Armor of God for Spiritual Authority in Battle

Are you coming up against your giants in someone else’s armor?

Are you trying to solve life’s problems and battling the enemy the way someone else advises or the way someone else handled a similar issue, or are you going to God and putting on the only armor you need; the full armor of God?

The Full Armor of God

Ephesians 6:10-18:

Finally, be strong in the Lord and in His mighty power. Put on the full armor of God, so that you are able to stand against the schemes of the devil. For our struggle is not against flesh and blood, but against the rulers, against the powers, against the worldly forces of this darkness, and against the spiritual forces of wickedness in the heavenly places. 

Therefore, take up the full armor of God, so that you may be able to resist when the times are evil, and after you have done everything, to stand firm. Stand firm then! Buckle the belt of truth around your waist, and put on the breastplate of righteousness. Strap up your feet in readiness with the Good News of shalom

Above all, take up the shield of faith with which you will be able to extinguish all the flaming arrows of the evil one. And take the helmet of salvation and the sword of the Spirit, which is the word of God. 

Pray in the Ruach (Spirit) on every occasion, with all kinds of prayers and requests. With this in mind, keep alert with perseverance and supplication for all the kedoshim (holy ones).

Test Everything

David tried on the armor Saul gave him and found it didn’t fit. He knew he could not battle his enemy in armor not meant for him.

God doesn’t want us doing things the way other people have. Sure, we should seek godly counsel but at the end of the day, we have to be sure it is what God wants for us.

We need to seek Him in His Word and in prayer.

Everything must be measured up against the Word of God.

1 Thessalonians 5:21:

but test all things, hold fast to what is good,


Facing your Goliaths mean that, like David, you have to give the battle to the Lord. Let the Lord go before you into battle!

This is not a physical battle but a spiritual one, and your spiritual authority doesn’t lie in your own power or someone else’s solutions. It is found in God alone!

Are you going up against your giants in someone else's armor? Click To Tweet

David did not want to wear Saul’s armor, not only because it was too large but because it was untested in battle for him. Put on the full armor of God, not the armor of man!

Test everything! Don’t assume because something works for someone else that it will work for you!

Don’t try facing your Goliath in someone else’s armor! Let the Lord lead you!
