Here we have very clear evidence of an escape that was originated, planned and engineered by God. It required the cooperative preparation of those who were escaping, because Noah and his sons had to prepare by building the place in which they were going to escape. They were surrounded by worldwide trouble that they could not completely flee from, and so God gathered them into one place while the devastation was going on.
They were prepared both physically in making the ark and spiritually in being righteous before God. The two were working together, the physical and the spiritual.
Interesting words! Comforting words! Now that's the kind of escape that one wants to be on. Again hold your finger in the book of Genesis, we'll go all the way back in the New Testament to II Peter 2:6-9.
