Psalm 7:9 Oh let the wickedness of the wicked come to an end; but establish the just: for the righteous God trieth the hearts and reins.

Human judges can get it wrong, God who judges the hearts and actions of man is right in every judgment. This is a character of God in His interaction with His creation. If we are to trust this God who is Holy, Loving and Just, then He must be right, all the time.

Malachi 3:6 For I am the Lord, I change not; therefore ye sons of Jacob are not consumed.

If He were to change, that would indicate our God had been wrong. We depend on that in the promises God makes to us, in that He will not change.

2 Corinthians 1:20 For all the promises of God in him are yea, and in him Amen, unto the glory of God by us.

Yea, meaning yes, His promise is true and Amen, meaning let it be done. Putting it in a different perspective, God’s righteousness is God’s Holiness in action.

Another aspect of being right in everything is truth. Because He is the Righteous God He is the only reliable source of truth. His antithesis is Satan, the father of lies. Because Satan speaks the spirit language he can speak lies to us. Since this is true our only hope of knowing the truth is in knowing God.

John 14:6a Jesus saith unto him, I am the way, the truth, and the life:

John 14:16-18 And I will pray the Father, and he shall give you another Comforter, that he may abide with you for ever; Even the Spirit of truth; whom the world cannot receive, because it seeth him not, neither knoweth him: but ye know him; for he dwelleth with you, and shall be in you. I will not leave you comfortless: I will come to you.

The Holy Spirit, the third person, is the Spirit of Truth.
