The Law of His God is in His Heart...

 The mouth of the righteous speaks wisdom,

And his tongue talks of justice.

31 The law of his God is in his heart;

None of his steps shall slide.—Psalm 37:30-31

There is only one way that my mouth can speak wisdom and my tongue talk of justice...by the Spirit of my God who dwells in me. 

18 For I know that in me (that is, in my flesh) nothing good dwells; for to will is present with me, but how to perform what is good I do not find.

22 For I delight in the law of God according to the inward man. 23 But I see another law in my members, warring against the law of my mind, and bringing me into captivity to the law of sin which is in my members. 24 O wretched man that I am! Who will deliver me from this body of death? 25 I thank God—through Jesus Christ our Lord!—Romans 7:18;22-25

It is my God who places His good and right desires on my heart.  

It is my God who directs my steps to walk in those works He prepared beforehand

It is my God who rules and overrules all in my life for my good and His glory. 

It is my God who goes before me and makes my way straight before my face. 

It is my God who upholds me with His righteous right hand and keeps me from falling. 

It is my God’s goodness and mercy that follow hard after me...I can’t outrun them. 

It is my God who leads me in righteousness and in the way everlasting. 

Beloved...step by step our God leads us as a father leads a child.  We may be sorely tried and tossed to and fro by Satan’s minions, but God will never leave us in the hands of our enemies.  In Him we live and move and have our being.  In Christ we are safe. 

31 What then shall we say to these things? If God is for us, who can be against us? 32 He who did not spare His own Son, but delivered Him up for us all, how shall He not with Him also freely give us all things? 33 Who shall bring a charge against God's elect? It is God who justifies. 34 Who is he who condemns? It is Christ who died, and furthermore is also risen, who is even at the right hand of God, who also makes intercession for us. 35 Who shall separate us from the love of Christ? Shall tribulation, or distress, or persecution, or famine, or nakedness, or peril, or sword? 36 As it is written:

"For Your sake we are killed all day long;

We are accounted as sheep for the slaughter."

37 Yet in all these things we are more than conquerors through Him who loved us. 38 For I am persuaded that neither death nor life, nor angels nor principalities nor powers, nor things present nor things to come, 39 nor height nor depth, nor any other created thing, shall be able to separate us from the love of God which is in Christ Jesus our Lord.—Romans 8:31-39
