“I give you my word” is often used when making a promise, but how long is it valid? Our words and promises will expire at some point, because we are not eternal; God, however, is. The Bible gives us His word, His living word. Hold on firmly to this and all other promises He’s made, because His word doesn’t expire.
Heaven and earth will pass away, but my words will never pass away. (Matthew 24:35 NIV)
