Why God exalted His Word above His Name?

"...for You have magnified Your word above all Your name" Psalms 138:2.

In the Old Testament God proved that His name was above all other names. No other god could compete with Him ever. The Egyptian gods failed. The gods of the 7 nations that lived in the promised land could not protect those nations from the God of Israel. Baal that Jezebel worshiped, could not protect neither her, nor her prophets when the wrath of God eventually came for the worship of the idols and the killing of God's people. God's authority stood above everything throughout ages. Yet, God Himself exalted His own word above His name. Why?

The heathen rules that reigned had their own laws, but often they could break them at their will. They could break even the laws they issued, because it was beneficial for them. Thus, they exalted themselves or their names above their own words. Our God is a God who never lies. He would not tell you to do what He is not willing to do Himself. If He tells us to forgive 7 times 70 per day, that is something He would do for you and me. You can always trust Him, because He would never break His word. No circumstances in the world, sky, under the earth or wherever could cause Him to adapt His word or change it. Our circumstances change and we do not commit to what we have promised. God always remains faithful to what He has promised. His mood does not influence His choices, which often happens to us. 

He identifies Himself with His word. His character is built on it. He created the world by His word, and the Universe is upheld by His word. It is stronger than the law of gravity and all natural powers combined. Thus, the most solid foundation for our trust in Him is His word - the Bible. He reveals Himself to us through the word. We see His character in it. His promises, will, and commandments for us are all written in the Word. He wouldn't promise us, or tell us something to do, which was not previously written in the Word. So, read the Word and grow your faith, for it is an unshakable foundation for you to build your trust in God.
