Unlike us, God never fails to keep His promises. The Bible is filled with His promises, and one of His promises is that His word will never fail to fulfill His purposes. In this passage, we learn that this word from God can never be destroyed which is contained the scriptures.
Bible is not an instruction manual on how to go to Heaven. It’s a Book given to us by God through His servants, primarily meant to reveal Himself and His plan of redemption for the sinners. It’s only then that the Bible is meant as God’s law for redeemed sinners like us, to walk in the path of righteousness. In this passage, we learn how the Bible is also meant to bring us comfort.
Christian life is about learning to trust God simply because of His unfailing love towards us as His children, and also for God’s faithfulness in keeping promises throughout history. The reason why trusting and believing in God is essential for us to persevere in faith is because we’re incapable of handling circumstances and uncertainties in life by our own strength and wisdom. This passage shows us how we’re called to keep believing in God’s promises especially when the situation might appear unfavorable.
