We need moral measurements as well as ways means to measuring time, weights, and distance.
Therefore we must rely on Biblical fundamental truths.
The Scriptures, both the Old and New Testament, are verbally inspired by God and are the revelation of God to man, the infallible, authoritative rule of faith and conduct.
16 All Scripture is inspired by God and profitable for teaching, for reproof, for correction, for training in righteousness; 17 so that the man of God may be adequate, equipped for every good work. 2 Timothy 3:14-17
