My mercy will I keep for him for evermore, and My covenant shall stand fast with him. His seed also will I make to endure for ever, and his throne as the days of heaven.
If his children forsake My law, and walk not in My judgments; if they break My statutes, and keep not My commandments; then will I visit their transgression with the rod, and their iniquity with stripes.
Nevertheless My lovingkindness will I not utterly take from him, nor suffer My faithfulness to fail. My covenant will I not break, nor alter the thing that is gone out of My lips.
Once have I sworn by My holiness that I will not lie unto David. Psalm 89:28-35

And He turned Him unto His disciples, and said privately,
“Blessed are the eyes which see the things that ye see: for I tell you, that many prophets and kings have desired to see those things which ye see, and have not seen them; and to hear those things which ye hear, and have not heard them. Luke 10:23-24

Blessed are those who see that the promises of God cannot be diminished, overcome, defeated, or destroyed. The word of the LORD stands sure forever.
