One of the exciting battles in spiritual warfare recorded in Bible centers around the anointed David's exile in the wilderness where King Saul tried to find him to eliminate him as a competitor for the throne of Israel. The warfare was both physical and spiritual.
David actually had the chance to kill King Saul who fought Israel's wars for nearly four decades but David observed the rule of not touching the Lord's anointed. A Saint is no ordinary believer and when Saul got the wrong thought in his heart to kill David to preserve his dynasty; the LORD wanted him to have every chance to repent of it and preserve the holy life he had lived as a warrier king.
Saul did repent of it at times, but could not restrain his own passions under extreme pressure from his own attempts to preserve his reign under his own power.
David gained access to King Saul as a singer of holy songs on the harp. When David David ministered to the King musically, the demons who oppressed him could not stay in the divine Presence. Singing in the beauties of holiness was a tool in David's spiritual warfare tool box.
The stone David threw skillfully at Goliath by faith was helped by the Spirit of the Lord although the giant never knew he was fighting against angel of the Lord. We do not war alone.
"IF THE LORD BE WITH US, WHO CAN BE AGAINST US?":
We have the Word of God here to consider, that David wrote concerning his spiritual warfare with Saul. The Ziphims came as traitors to Saul David hid himself with them. We are not talking about one man, but about six hundred. Quite a few of the dispossessed and disenchanted of Israel had joined David in the wilderness and they had become his armed militia.
"Hear my prayer, O God; give ear to the words of my mouth.
For strangers are risen up against me, and oppressors seek after my soul: they have not set God before them. Selah.
Behold, God is my helper: the Lord is with them that uphold my soul.
He shall reward evil unto my enemies: cut them off in your truth.
I will freely sacrifice unto you: I will praise your name, O LORD; for it is good.
For he has delivered me out of all trouble: and my eye has seen his desire upon my enemies." (Psalm 54:1/7)
David was in the Spirit much of the time where "THE ANOINTING THAT ABIDES WITHIN TEACHES ALL THINGS." Spiritual prayers were another of the tools in his spiritual tool box.
David is a Prophet, but few notice it when reading their Bible. His prophecies are so subtle, they are easily missed. When David wrote that God would reward evil unto his enemies, he was speaking as a Prophet. Then he commanded the LORD. "Cut them off in your truth."
David's prayer reads very much like a lawyer's brief to the judge in a court room, though he is speaking to the Judge of all the earth.
He closes with promises of good things toward the LORD, saying he would "freely sacrifice" and "praise" the LORD'S name. David apparently knew how to offer up sacrifices unto the LORD before the first temple was built, and he also seemed to be privy to the knowledge of the secret name of the LORD which few men know.
David is a spiritual giant historically, so we can learn a lot from his warfare. He was not fighting against strangers and oppressors alone. God provided him a little army and David used them well. And he used his ability to inquire of the LORD before going into battle.
Read David. You'll be glad you did.
