One of the Hebrew words that describes God is Emeth and is often translated as Truth. Moses heard God use this word speaking of Himself: "The Lord, The Lord God...abundant in goodness and truth" (Exodus 34:6 KJV).
Because God is truth, His words are reliable. Has God given you a promise that is yet unfulfilled? Repeatedly He assures us that He keeps His word: "God is not human, that he should lie, not a human being, that he should change his mind. Does he speak and then not act? Does he promise and not fulfill?" (Num. 23:19).
We might make promises rashly or make promises we cannot fulfill. But such limitations never hamper our omnipotent God. He even fulfills His promise to give us the desires of our hearts as He promises in Psalm 37:4. He did that for Moses who asked to cross over into Canaan. Fifteen centuries later God said, "Moses, I am sending you to the Promised Land to visit. You will visit with the Son of God on the Mount of Transfiguration." (See Matthew 17:1-3.)
Our Father declares, "I will not violate my covenant or alter what my lips have uttered" (Psalm 89:34). In God's words of promise there is no exaggeration. He may mean more, but He can not mean less; for He is "A faithful God who does no wrong,upright and just is he" (Deut. 32:4). "He who is the Glory of Israel does not lie or change his mind; for he is not a human being, that he should change his mind" (1 Sam. 15:29).
All of His Word was written for you. Take His Word when you go to Him and ask Him to do exactly what He has said. Use the Word in your praying: lovingly, humbly, but boldly holding God to His Word. He will not violate His promise to you. He is Truth and He is bound to His promise.
Because David knew God to be Truth, he reverently, but with holy insistence, prayed for the fulfillment of God's promise. "Do as you promised...that your name will be great forever...O Lord, you are God! You have promised these good things to your servant" (1 Chronicles 17:23-24 KJV).
Dear God, what a consolation it is to know that You always keep Your promises.
"You know with all your heart and soul that not one of all the good promises the Lord your God gave you has failed. Every promise has been fulfilled; not one has failed" (Josh. 23:14).
