When tuning a guitar you find the exact pitch for the top string- the E string- and tune the other strings according to the accuracy of that E string. If the standard of the E string is off, the rest of the strings will also be off and the sound will be chaotic and not nice to listen to. (Trust me there's nothing worse to listen to than an untuned guitar! 😜) It's the same with truth. If we have no absolute standard for truth, everything in our lives will be out of balance and out of tune. Just as 2+2 will forever and always = 4, whether or not we like it, agree with it, feel like it or find it culturally relevant, Gods word will always be our standard; the unchanging, solid, timeless, absolute measurement for truth. Lord knows, my feelings change minute by minute and my perspective has not always proven to be correct. There must be a standard that is bigger than me, stronger than me, wiser than me, more loving than me and transcending culture and time. Because if it's all relying on my own understanding, then my foundation will not remain solid when life gets shaky and seasons change. If it's all up to me to tune the strings without a standard to go by, then my sound will be confusing and my message will be muddled. Our lives are meant to be a beautiful song based on the unchanging, solid standard of that top string. Gods truth is our E-string.
