1:37

no declaration will be impossible for God: Or “no word from God will ever fail.” Or possibly, “nothing will be impossible for God.” The Greek word rheʹma, rendered “declaration,” can refer to “a word; a saying; a declaration.” Or it can refer to “a thing; the thing spoken of,” whether an event, an action described, or the result of what has been declared. Although the Greek text could be rendered in different ways, the overall meaning remains the same, namely, that nothing is impossible as far as God is concerned or with respect to any of his promises. The wording here is similar to the Septuagint rendering of Ge 18:14, where Jehovah assured Abraham that his wife, Sarah, would give birth to Isaac in her old age.
