Just as it was in the days of Noah, page-7

According to scripture God promised that the rainbow is a sign that the days of Noah would not be repeated.

Genesis 9:12-15 New International Version (NIV) Bold is mine
¹² And God said, “This is the sign of the covenant I am making between me and you and every living creature with you, a covenant for all generations to come: ¹³ I have set my rainbow in the clouds, and it will be the sign of the covenant between me and the earth. ¹⁴ Whenever I bring clouds over the earth and the rainbow appears in the clouds, ¹⁵ I will remember my covenant between me and you and all living creatures of every kind. Never again will the waters become a flood to destroy all life.
