The continuation of the universe and the earth all depend upon the omnipotence and immutability of Jesus Christ (Colossians 1:17, Hebrews 1:3).
“Scientific laws” is a misnomer. They are “Divine laws.”
Science can observe and classify. Only God can guarantee the continuation of these laws.
The universe will not always exist as it does at the present (2 Peter 3:10-12, Revelation 20:11).
Known scientific laws depend solely on the faithfulness of God (Colossians 1:17).
The reason for preserving the universe is to resolve the angelic conflict in human history and to bring many sons into glory (Hebrews 2:10).
The Word of God will survive the destruction of the universe (2 Peter 3:10).
Regenerate man in resurrection body will live forever and survive the destruction of the present universe (Hebrews 12:26-28).
It is Jesus Christ who holds the universe together by the power of His Word (Hebrews 1:3) and holds back eternity so everyone will have the opportunity to appropriate the grace of God. This begins at the point of faith in Jesus Christ, so the angelic conflict will be resolved and ultimately God will be glorified forever and ever.
