“And after the seven days the floodwaters came on the earth.”‭‭Genesis‬ ‭7:10‬ ‭NIV‬‬
To me it reads that nothing happened outside the ark for seven days. God said he was to flood the world but here they were in the Ark and nothing was happening. 

I bet people outside the ark felt that Noah had lost his mind. They wouldn’t have had a seven day forecast then, so if they were worried, you would think by day seven the locals would have been contempt in their normal day lives. 

I believe here God was again showing that He is in control. He will flood the earth as He said He would, but when He was ready. 

Gods timing is always perfect. We might not always understand why things happen when they do, or don’t happen when we want them to. We should try to live in faith knowing that God knows best and He will make it happen when He wants if it is His will.
