On the third day of creation, God gathered the waters, allowing dry land to appear, which He called earth, and the waters which He named seas. God did not create the land anew, but He placed everything precisely where He commanded it to be. He then commanded the earth to produce vegetation with plants yielding seed and fruit trees bearing fruit, each according to its kind. This third day of creation further reveals God’s order and intentionality. His preparation of land and food showed God's care in providing sustenance for the creatures He would create later. By the end of the third day, God saw that everything was good, aligning perfectly with His design and purpose, reflecting His nature as a God of order, not chaos.
As in each of God's acts of creation, He commands what is to be done, and it is done. God says for the waters to be gathered together and for the land to appear, "And it was so." Now, God commands the earth itself to "sprout vegetation…And it was so." The earth brings forth what God commands it to bring forth and in the exact manner in which He commands it—plants which yield seed, fruit which does the same, and "each according to its kind." In other words, a rose does not produce a seed capable of growing a pine tree. God here commands not only that the plants come forth, but that they are prepared to continue to regenerate themselves in their unique, individual aspects. We will see later that God commands the same standard for each living creature He creates. The continuation of a species is made possible because God has declared it to be so from the beginning of creation. God is a God of order, not chaos (1 Corinthians 14:33).
We also see God’s goodness and intentionality here as He creates food for living creatures He has already planned to make. Notice how He lovingly prepares the living space for His creation—not only establishing the ability for each plant to reproduce itself and be widely available, but also creating those things that will sustain the creatures He will create. God does not create the ox and then, after the fact, realize that He needs to create food for it. Instead, He intentionally creates the space and food for the ox before creating it.
After the third day of creation, God once again looked upon all that He had done and declared that it was "good;” it is what God intended. It was excellent and pleasing. The third day concludes with the same words as the other days: "And there was evening and there was morning, the third day." Three literal days have passed and God created the heavens, earth, light, land, seas, and plants.
