Why do we have this measurement tool ingrained in almost everything produced? Because we desire the best outcome and somewhere along the way A Standard was set and possibly reset to compare all future results. For example, there is a safety standard for new vehicles that has to be met before a new car, truck or SUV can be sold and driven.
The spiritual revelation to this is that the Old Testament, especially The Law, was meant to say loudly, "You will Never measure up to God's Standard - Perfection!" While in the New Testament, God says even louder, "BUT, I will provide The Standard to stand and die and live again in your place! He is my Son - Jesus." Our part is to accept Jesus as The Standard of our lives and base our decisions in life out of our new-found relationship with Christ - The Standard.
The spiritual application is found in Proverbs 16:11 -
- "Honest scales and balances belong to the Lord; all the weights in the bag are of his making."
The "weights in the bag" of God's making are things like truth, honor, love, joy, peace, forbearance, kindness, goodness, faithfulness, gentleness and self-control. I am sure there are more, however, when Christians are faced with decisions - God's "honest scales and balances" are what I encourage you to use. You can research His verdicts on matters in The Bible. Then you will be able to know and move according to a more higher and perfect way - His Standard.
