For he spake, and it was done; he commanded, and it stood fast. (Psalms 33:9) *Introduction - God speaking in creation.* *1/ God speaking in Old Testament times. 2/ Jesus speaking on earth with the same power. 3/ Jesus speaking in Gospel days. 4/ Jesus speaking at the end of the world.* **Sermon summary:** The sermon explores the consistent theme of God working through His Word, tracing this principle from the creation of the heavens to the final resurrection. It highlights how divine authority was demonstrated in the Old Testament through figures like Noah, Abraham, and Moses, and how Jesus Christ evidenced the same power during His earthly ministry by healing and commanding nature with a single word. The message emphasizes that in the current age of grace, salvation is exclusively accomplished through the preaching of the Gospel, as faith comes by hearing the Word of God. This theological framework culminates in the expectation of the Second Coming, where the voice of the Lord will again effect a final division between the saved and the lost. The tone is instructional and exhortative, urging believers to value the Scriptures as the sole and sufficient means of spiritual life and eternal hope.
