This Greek name of God simply refers to one who places, lays, or sets the law, and then dispenses justice. Our justice systems include legislation, judgment, and corrections. God acts in all three capacities. The titles Lawgiver and Judge highlight two of them.
Lawgiver and Judge in Greek:
Nomothetēs kai kritēs
Strong’s Concordance numbers: 3550, 2923
Bible reference: Jas. 4:12
There is only one Lawgiver and Judge, the one who is able to save and destroy. But you—who are you to judge your neighbor? (James 4:12 NIV)
In the Old Testament God is described as our Lawgiver and several names throughout the Bible call God the Judge.
