“This God--His way is perfect;
The word of the LORD proves true;
He is a shield for all those who take refuge in Him.”  2 Samuel 22:31 
(Psalm 18:30 repeats this verse.)

God’s way is perfect (complete); proven to those who trust Him, He is a shield!  This verse attests to God’s divine ways; to His divine perfection and His divine refuge.

Deuteronomy 32:4 tells us,
“The Rock!  His work is perfect,
For all His ways are just;
A God of faithfulness and without injustice,
Righteous and upright is He.”
(Along with verse 3, we often sing this portion of Scripture  in our worship service.  There are many portions of Scripture that tell of the glories of God  that have been set to music.  This is a wonderful way to give honor and praise to the Lord through the day and at difficult times.  I find it to be a great way to memorize Scripture as well.)

*His divine ways:
“The LORD is righteous in all His ways and kind in all His works.
The LORD is near to all who call on Him, to all who call on Him in truth.” 
Psalm 145:17-18

“For as the heavens are higher than the earth, 
So are My ways higher than your ways
And My thoughts than your thoughts.”  Isaiah 55:9

“…the ways of the LORD are right,
And the righteous walk in them,
But transgressors stumble in them.”  Hosea 14:9

“Oh, the depth of the riches both of the wisdom and knowledge of God!  How unsearchable are His judgments and unfathomable His ways!”  
Romans 11:33

* His divine protection:
As well as the above Scriptures we add Ecclesiastes 3:14,
“I know that whatever God does, 
It shall be forever.
Nothing can be added to it,
And nothing taken from it.
God does it, that man should fear (be in awe) before Him.”

*His divine refuge:
“For He will hide me in His shelter in the day of trouble;
He will conceal me under the cover of His tent;
He will lift me high upon a rock.”  Psalm 27:5 

“God is our refuge and strength, 
A very present help in trouble.”  Psalm 46:1

“In the fear (reverence) of the LORD there is strong confidence,
And His children will have refuge.”  Proverbs 14:26

“The name of the LORD is a strong tower;
The righteous run into it and are safe.”  Proverbs 18:10

Isaiah 25:4 gives a brief but wonderful summary of God’s divine refuge and wall of protection for His own,
“For Thou hast been a defense for the helpless,
A defense for the needy in his distress,
A refuge from the storm, a shade from the heat;
For the breath of the ruthless is like a rainstorm against a wall.”

And we join our voices and sing the song of Moses and the song of the Lamb in Revelation 15:3-4 and proclaim:
“Great and amazing are Your deeds, O Lord God the Almighty!
Just and true are Your ways, O King of the nations!
Who will not fear, O Lord, and glorify Your name?
For You alone are holy.  
All nations will come and worship You, for Your righteous acts have been revealed.”

All hail King Jesus bless His Name forever, He has reconciled us to our Heavenly Father and  all these sure and true things spoken above are ours in Him!  Hallelujah!
