When Noah was to to build a arc he had no idea why he was building it. He and his family just had to get through it. Although there is no definitive time as to how long it took Noah to build the Ark, it is hinted that it took one hundred and twenty years. That does not account for the time it took to gather two of every animal. When most read a story like this, they find it very hard to believe. Because most conceive time like it is today, not realizing that time was totally different back then. The basic thing to remember is that no matter the question as to why something has to be done a certain way as opposed to fast and filled with short cuts. Is the difference in the outcome. When God made his plan for you, it took time. And the steps that are ordered take time as well. You have to remember firstly that lessons can be learned from every experience in life. Secondly if there is no work put in ,why should the expectation be any higher? You just have to work through it.
2 Peter 3:9 The Lord is not slow to fulfill his promise as some count slowness, but is patient toward you, not wishing that any should perish, but that all should reach repentance.
