Deuteronomy 32:4 (KJV)  He is the Rock, his work is perfect: for all his ways are judgment: a God of truth and without iniquity, just and right is he. 

All that the LORD does is with judgment and justice. They are measured according to His commandments and there is nothing amiss in His dealings. His work is perfect. He is the Rock, altogether stable and reliable.

He is a God of truth and without iniquity therefore just and right is He and faithfulness characterises Him. There is no variableness nor shadow of turning (James 1:17).

His people can safely trust in Him to guide them in the right way. Amen.
