“So now may the fear of the Lord be on you. Consider and act well because there is no injustice, partiality, or bribe taking with the Lord our God.” 2 Chronicles 19.7
The children of God know that with Him it is yes, yes and no, no. There is no being clever or deceitful. There is no half-faith, but a wholesome faith and obedience. They also act right towards their neighbor: they honour their word, are solicitous, and are happy to please the God of Justice.
