THE GOD OF TRUTH
27He said, “Blessed be the Lord, the God of my master Abraham, who has not forsaken His lovingkindness and His truth toward my master; as for me, the Lord has guided me in the way to the house of my master’s brothers.” (Ge 24:27 NASB)
5The Lord descended in the cloud and stood there with him as he called upon the name of the Lord. 6Then the Lord passed by in front of him and proclaimed, “The Lord, the Lord God, compassionate and gracious, slow to anger, and abounding in lovingkindness and truth; 7who keeps lovingkindness for thousands, who forgives iniquity, transgression and sin; yet He will by no means leave the guilty unpunished, visiting the iniquity of fathers on the children and on the grandchildren to the third and fourth generations.” (Ex 34:5–7 NASB)
5Lead me in Your truth and teach me, For You are the God of my salvation; For You I wait all the day. (Ps 25:5 NASB)
5Into Your hand I commit my spirit; You have ransomed me, O Lord, God of truth. (Ps 31:5 NASB)
10But the Lord is the true God; He is the living God and the everlasting King. At His wrath the earth quakes, And the nations cannot endure His indignation. (Je 10:10 NASB)
16“Because he who is blessed in the earth Will be blessed by the God of truth; And he who swears in the earth Will swear by the God of truth; Because the former troubles are forgotten, And because they are hidden from My sight! (Is 65:16 NASB)
A. The Hebrew word for ‘truth,’ emet, is a derivative of the word aman, where we get the word “amen,” meaning to confirm, support, uphold, or express certainty. Emet is used 127 times in the OT and means firmness or certainty, thus rendered “truth” or “faithful / faithfulness” the majority of the time.
Faithfulness is the quality that provides an appropriate ground for confidence, which gives support to trust on the part of those who depend on the faithful one. Truth is that firm conformity to reality that proves to be wholly reliable, so that those who accept a statement may depend on it that it will not turn out to be false or deceitful.
11The Lord has sworn to David A truth from which He will not turn back: “Of the fruit of your body I will set upon your throne. (Ps 132:11 NASB)
B. Often in the OT, the word emet when referring to God, is closely joined with God’s merciful lovingkindness (Heb, hesed) in His relating to man. This highlights God’s enduring reliability and commitment to His covenant promises in spite of man’s unfaithful commitments; as well as shows His kindness in merciful love toward those who are bent to turn to their own way.
C. In addition to a description of God Himself and His relation to creation, the idea of emet is, in turn, required of men in relationship with Him.
14“Now, therefore, fear the Lord and serve Him in sincerity and truth; and put away the gods which your fathers served beyond the River and in Egypt, and serve the Lord. (Jos 24:14 NASB)
1O Lord, who may abide in Your tent? Who may dwell on Your holy hill? 2He who walks with integrity, and works righteousness, And speaks truth in his heart. (Ps 15:1-2 NASB)
6Behold, You desire truth in the innermost being, And in the hidden part You will make me know wisdom. (Ps 51:6 NASB)
D. Out of this same word group, we get the Hebrew word emunah, which is largely translated as “faith” or “faithful.” The term applies to God Himself (Dt. 32:4) as well as His works (Ps. 33:4) and words (Ps. 119:86). Emunah is also used to refer to the lives of men relating to God, and characteristic of those lives that are justified in God’s sight (Hab. 2:4). The truth and dependability of God and His word establishes a way for a response of trust and fidelity from the lives of men (Ps. 119:30).
E. It’s important to recognize the general categories of language associated with these ideas, as we turn to the NT ideas of “truth” and “faith.”
