Jesus is depicted dying on the Cross for our sins. In my opinion, it was dark when Jesus was crucified. The darkness signifies their cruelty towards Him as they did not know that He was the Son of God.
Our faithful God has worked miracles to many who are diagnosed medically barren. This is evident in the Bible and even in my wife, who was told that she would have difficulty conceiving but is now a mother of three. Thus, we should willingly receive the hope of life in Jesus with open hearts and thanksgiving!
God was angry when people did bad things and He wanted to punish them. However, Uncle Noah was a good man who listened to God, and God protected Uncle Noah by asking him to build a big boat to keep him, his family and some animals safe. God set a rainbow in the sky after the flood, promising Uncle Noah that He would never flood the earth again.
