Why, Lord, do You speak to us the Word of warning and the promise of blessing?

Why, Lord, do You speak to us the Word of warning and the promise of blessing? There is a good way to which we must turn - and there's also a bad way from which we turn. How can we really appreciate and embrace the good way if we do not see the clear contrast between the good way and the bad way? Help us, Lord, to choose the good way - to choose Jesus, who is "the Way, the Truth and the Life" (John 14:6).
