Psalm 119:89-91
Forever, O Lord, Thy word is settled in Heaven. Thy faithfulness continues throughout all generations; Thou didst establish the Earth, and it stands. They stand this day according to Thine ordinances, for all things are Thy servants.
God is God, and we are not. God is sovereign over all Creation, for He made it all, and He rules it all. What He established in this Universe continues, because they all obey His ordinances, His rules for them, and they follow them. Only Angels and Man have the authority to disobey His rules; the Angels that sinned were created without the ability to die, so they cannot be redeemed. Man sinned also, but God made Mankind with the ability to live or die, so because we sinned, we can have a substitute to die in our place, so we can live. In the Old Testament, God allowed an animal to die for the sinner, and he can now be forgiven, because the death-price has been paid. When Jesus died, He was the Perfect Sacrifice, Who paid our human death in our place, so now there needs to be no more sacrifices, because what He paid was perfect and forever.
So now we have a truly free choice to obey, and love Him; or to rebel and refuse Him. We can live in His power, as His Spirit has come to live in us, and we are able to now obey His rules; or if we refuse Him, we will perish.
God is Truth, and what He has said will prevail throughout all time, unchangeable and unalterable. Even though this Heaven and this Earth may perish (when He decides to destroy it), His Word will never pass away, through all eternity.
Even so, come, Lord Jesus!
