1 Samuel 19, 1 Corinthians 1, Lamentations 4, Psalm 35

1 Samuel 19:20-24
In Scripture, God delivers and protects people in diverse and unusual ways. 
To save Noah and his family, in Genesis 6:14, God told Noah to build an ark, even though it had never rained. 
To protect Sarah, in Genesis 20:3, God told Abimelech he was a dead man because he had taken Abraham's wife.
To deliver the Israelites, in Exodus 14:16, God parted the sea and allowed the people to escape on dry ground.
To intercede for Balaam, in Numbers 22:28, God had a donkey speak. 
To destroy Jericho, in Joshua 6:20, God flattened the walls of Jericho by having the people march, shout, and blow trumpets.
With all of these examples, I think this is the most unusual act of deliverance in the Old Testament.  Saul is determined to kill David, even though his son and daughter have done everything they can to frustrate his plan.  After David escapes to Samuel, Saul sent three separate groups to kill David.  Jonathan and Michal were unsuccessful in protecting David, but God wasn't. 
Of all the ways God could have saved David from Saul's hand, who but the LORD God Almighty would have thought of sending His Spirit upon these men.  They not only forget about David, they begin prophesying, that is, praising and glorifying the LORD.  Then Saul, refusing to see God's hand protecting David, went to Naioth to do the job himself.  You know what happened.
The Holy Spirit coming on men whose plan is to kill David is a most unusual method of deliverance but not the most astonishing.  In the New Testament, we are told God Himself, in the likeness of man, came and lived among sinful men to deliver them.  Immanuel, God with us, allowed Himself to be placed on a cross, after being beaten mercilessly, to deliver His people from their just punishment. 
Jesus came to save, protect, deliver and intercede for His people by destroying the works of the devil.  All the incredible, marvelous, and surprising deliverances of God's people point to the one true salvation - Jesus Christ our Lord and Savior.
1 Corinthians 1:2
"Those sanctified in Christ Jesus, called to be saints together with all those who in every place call upon the name of our Lord Jesus Christ, both their Lord and ours."
Through years of reading the Bible, I have paid particular attention to different aspects of the faith and keep a running record for myself.  I have lists such as, Scriptural prayers, promises, names of God and words describing salvation.  Descriptions of the church is the longest.  There are so many ways God describes those He gave to His Son.  1 Corinthians 1:2 is an excellent example. 
Paul starts by calling us the "church of God."  The Greek word for church is ekklesia which comes from the root word laleo which means to call.  The church is the "called ones."  Paul makes that point by describing the church as those "called to be saints."  He uses the same word to describe himself as an apostle in verse one, "Paul, called by the will of God to be an apostle."  Just as Paul was called by the will of God, so, too, are those who make up the church of God.  
The other description Paul uses to explain the church is " those sanctified in Christ Jesus."  In 1 Corinthians 7:14 the word sanctified is translated as "holy." 
So the church of God consists of those effectually called by God to be holy saints.  Exodus 28:36 says the priests wear an engraved signet that reads "Holy to the LORD."  In 1 Peter 2:5-9, the church is described as a holy priesthood, a holy nation, a people for God's own possession.
As a believer, is that how you see yourself?  You should because if you are in Christ Jesus, that is how the Living God sees you!
Lord Jesus, thank You for sanctifying a people for Yourself through Your blood.  Thank You for effectually calling me.
