The Bible says God is the potter.
But now, O LORD, You are our Father; We are the clay, and You our potter; And all we are the work of Your hand.
The first day of creation was the equivalent of Him slapping His lump of clay on the wheel: on that day He created the physical dimension, time and space, none of which existed previously. On that day He created the matter He would then form into the earth, the sun, the moon, the stars and all living things over the following five days. Just as you would not look at the formless lump of clay on a potter’s wheel and say he’d done it badly but recognise he had to produce the material first before he could mould it into shape, so you cannot look at the start of God’s creative work, when He created the matter He would mould into the earth, and judge it as imperfect. In both cases you have to wait until it is finished before you can pass judgement.
Why did God do it that way? Why did He take six days and not do it instantly? I do not know. Perhaps the blind man might have asked why Jesus did not heal Him instantly
So He took the blind man by the hand and led him out of the town. And when He had spit on his eyes and put His hands on him, He asked him if he saw anything. And he looked up and said, "I see men like trees, walking." Then He put His hands on his eyes again and made him look up. And he was restored and saw everyone clearly.
The Israelites might have wondered why they couldn’t go straight up to Jericho and see the walls fall at their shout instead of having to walk around it 13 times
You shall march around the city, all you men of war; you shall go all around the city once. This you shall do six days. And seven priests shall bear seven trumpets of rams' horns before the ark. But the seventh day you shall march around the city seven times, and the priests shall blow the trumpets. It shall come to pass, when they make a long blast with the ram's horn, and when you hear the sound of the trumpet, that all the people shall shout with a great shout; then the wall of the city will fall down flat. And the people shall go up every man straight before him."
Naaman might have asked why he couldn’t be healed after dipping just once in the Jordan instead of seven times
So he went down and dipped seven times in the Jordan, according to the saying of the man of God; and his flesh was restored like the flesh of a little child, and he was clean.
2 Kings 5:14
Presumably it was to teach them something; and maybe God took six days over His creation in order to teach us how to live?
Six days you shall labor and do all your work, but the seventh day is the Sabbath of the LORD your God. In it you shall do no work: you, nor your son, nor your daughter, nor your male servant, nor your female servant, nor your cattle, nor your stranger who is within your gates. For in six days the LORD made the heavens and the earth, the sea, and all that is in them, and rested the seventh day. Therefore the LORD blessed the Sabbath day and hallowed it.
The Bible is God’s Word, and we can depend on it for the truth, as millions have over many centuries. Satan’s first lie was, “Has God said,” and he continues to try to put doubts into our minds. Well, God had said, and Adam and Eve suffered, along with the rest of the human race, because they doubted it. He spoke to them in order to protect them from deception, just as He has given His word to us for exactly the same reason. It is only by accepting it, and resisting the urge to compromise what it plainly says in order to accommodate theories originally dreamed up by people who want a universe that can create itself, that it can fulfil its purpose and guide us safely on our journey through life.
Your word is a lamp to my feet and a light to my path.
