Noach 5775

There are thousands of types of animals and birds in the world. Additionally, such an amount of creatures would require an incredible amount of food and space in order to multiply. The Ramban explains that it was a miracle that the ark was able to hold everything; the small was able to hold the large. Why then was the ark as big as it was? Why not make a smaller one and rely on the miracle? The Ramban goes on to say that the way miracles in the Torah work requires man to do whatever he can and the rest is left for Hashem. It is important to lead an active life and not to sit back and wait for things to happen. Hashem rewards those who put in effort.
