In Psalms today we get a quick verse that points out the unfailing Word of God, God does not lie. What God said back when the Bible was written holds true today all of these thousands of years later:
Psa 12:6 The words of the LORD are pure words; As silver tried in a furnace on the earth, refined seven times.
Back then metals were refined by the fire to remove their impurities, and if we tie that in to today’s verse, it means that God’s words and his promises are free from any impurities or falsehoods.
In this case, God’s covenant with us through Jesus where when we declare Christ as Lord is a pure promise, there are no takebacks.
That’s important to remember, because we as humans are constantly changing, our views and opinioins. our laws are forever being altered, because we are flakey and fickle creatures. God, on the other hand is unchanging, HIs promise that He made to us then when Christ was resurrected on the 3rd day is as true to us now as it was then.
