GOD IS BOUND BY HIS WORD
God is bound by His word. Just as an oath binds the people involved, His word binds Him to do what He says He will do. Binding Him to His word is not in the sense of forcing an unwilling person to perform an obligation but in the sense of God’s word is His ways; His nature.
He lives His word; His word is what he does. It is native to Him and He needs no persuasion to do His word.
