X. Why didn't Jesus return at the end of the 6th.day?
The reason is because no man knows the day or the hour when Jesus will return. (Matt.24:36)This includes this study. However, this study does reveal the urgency of the time and season. Jesus said, "occupy ( to busy one's self, i.e. to trade) until I come." (Luke.19:13) Besides, nobody knows if this is really the year 2017 because our calendars are not correct. Even if our calendar was correct, it is still a waste of time calculating the day or the hour because Jesus said, nobody knows except the Father. (Matt.24:36)
A. God did not tell Noah the exact time of the flood
"God saw that the wickedness of man was great in the earth, and that every imagination of the thoughts of his heart was only evil continually. And it repented  the Lord that he had made man on the earth, and it grieved him at his heart. And the Lord said, I will destroy man whom I have created from the face of the earth; both man, and beast, and the creeping thing, and the fowls of the air; for it repenteth me that I have made them. When God told Noah was that the end of all flesh has come up before Him, and He would destroy the earth, (Gen.6:1-13) NOTHING was said about "when." All that Noah was given was a pattern for the Ark and time to prepared. (Matt.24:36-37, Heb.11:7, 2Peter.3:1-9)
There was nothing about 120 years.
1. His job was to build according to the pattern
Noah's job was to "occupy" (busy himself Luke.19:13) by building an Ark according to the pattern. (Gen.6:14-22)Note: NOTHING was left to Noah's imagination! The same is true today because our minds are being renewed (Rom.12:1-2) and our imaginations are a mixture and completely unreliable.
2. Today we have the pattern
As it was in Noah's day, the same is true today. We do not know the exact time of the Second Coming, but we do have the pattern of God's Word to build by. (Matt.24:37-38, 1Cor.3:13-15) This 12 Phase series contains a blueprint from the Word of God for building your Ark which will preserve you in these last days. (The 5th. and 6th. days)
B. Noah did know that destruction was coming.
We do know that Jesus is returning(Matt.24:36-39, Luke.17:26-30) to "execute judgment upon all...that are ungodly..." (Jude.1:15, Gen.6:8-13) and we do knowthat in that destruction God's has promised to preserve Word us that have "found grace in the eyes of the Lord" (Eph.2:8, 1Peter.5:5-6) in The Lord Jesus Christ. C. We will know when to get on the Ark!
The apostle Paul told the Thessalonians "that that day should not overtake you as a thief. Ye are all children of the light, and children of the day." (1Thes.5:4-9) The reason that Noah knew when to get on the Ark is because he was not "asleep" (1Thes.5:6) but building according to the pattern that God gave to him. There was nothing left for his imagination. Noah could see because he built according to the pattern, that it was about time to get on the Ark.
Note: Noah could simply compare what he had built and what was left to built according to the pattern / blueprint. This pattern developed a "hearing ear" for the voice of God. (Gen.7:1, Matt.13:10-17, Rev.2:7, 11, 17, 29; 3:6, 13, 22)
D. Noah / Family / animals were safely in the Ark before destruction
The apostle Paul writes, "But ye, brethren, are not in darkness, that that day should overtake you as a thief. Ye are all the children of light, and the children of the day: we are not of the night, nor of darkness. Therefore let us not sleep, as do others; but let us watch and be sober." (1Thes.5:4-7) 1. This is an important point!
Noah would have suffered "loss" (1Cor.3:10-15)if he would have focused on the destruction and ignored the pattern to build and Ark. There are many today that are focusing on the "day of judgment and perdition of ungodly men" and ignoring the pattern to build, thinking that in a "twinkling of an eye" their Ark will be built. (Review: What about the Pre-Trib. Rapture? Phase.12, Other related Subjects)
Now is the time for preparation and building according to the pattern, as Noah did.
E. Think on this!
The thing that Noah built, was the thing that preserved him and his family! (Note: Phil.2:12) How many of God's people that have "found Grace in the eyes of the Lord" are, "By faith" preparing according to the pattern? (Heb.11:7) How many are allowing themselves to be "warned of God. How many are allowing the Spirit of God to lead them into "things not as seen yet?" (1Cor.2:1-14, John.16:12) How many "fear" God's word?
Noah's life depended on building the Ark. What are you depending on?(1Cor.3:10-15)
As it was in the days of Noah, "the heavens and the earth, which are NOW by the same word are kept in store" (2Peter.3:1-7) for the Second Coming of Christ.
This Phase 3 gives a time framework, and is not intended to predict the day or the hour of Christ's return. It is intended to present a picture of the urgency of the hour(2Peter.3:1-9) and to emphasize the building and completion of the Church, the Bride (Ark) before the Second Coming.
