“Heaven and earth will pass away, but my words will never pass away.” Matthew 24:35 NIV1984
Reliability is a rare commodity. We can put our trust on material things (like money or gadgets, etc.) but they never will last. Soon they are gone and we wonder why we trusted in them in the first place. We can trust in people (they can be friends or family) but there comes a time when our trust is betrayed. It also happens the other way around. We fail to live up to the trust given to us. In the end the word of God is the only thing in all the universe that is truly trustworthy, because it comes from God.
