How long did it take to build Noah’s ark, and where can I find the answer?

In I Peter 3:19, Christ preached through Noah just as He uses the Christian today, who are His ambassadors. (II Corinthians 5:20). God describes the people Noah preached to in Genesis 6:5, "...every imagination of the thoughts of his heart was only evil continually." They were prisoners to their own sin. The word prison is the Greek "phulake" and is never--anywhere in the New Testament--used in reference to Hell, or translated as such. This alone disproves the false claim of some that, "After you die and are in Hell, you get a second chance". That is exactly what Satan would like you to believe! Read Luke 16:19-31. Perhaps this man in Hell believed Satan’s lie that he would have a second chance; but, found out too late that he had been deceived.

When you die, your destiny is sealed forever. That is why the Lord stated, "...behold, now is the accepted time; behold, now is the day of Salvation." (II Corinthians 6:2). "It is a fearful thing to fall into the hands of the living God.", without Christ as your Savior. (Hebrews 11:31).

God destroyed millions during the flood, the multitude who didn’t believe. You can follow the multitude into Hell, or the minority into eternal life, it is your choice. John 3:36 makes it perfectly clear, "He that believeth on the Son hath everlasting life: and he that believeth not the Son shall not see life: but the wrath of God abideth on him."
