After God had first commanded Noah to build the ark, Genesis states that Noah was obedient to God— that he did according to all that God had commanded him (Genesis 6:22). For 120 years, Noah invested his time and energy in the construction of a massive ark. At last, the time came and God commanded Noah to enter the ark (Genesis 7:1). Continuing on, God told Noah the number of days the pre-flood world had left:
For after seven more days, I will send rain on the earth forty days and forty nights; and I will blot out from the face of the land every living thing that I have made. Noah did according to all that the LORD had commanded him. (Genesis 7:4-5)The pre-flood world had just seven days. The 120 years of mercy had quickly passed. There was now just one more week left.
One more week to breathe. One more week to live. One more week to sin.
And... one more week to repent. But just as the years before passed without repentance, so the last week also passed without repentance. Man refused to worship his Creator, preferring instead to dwell with demons. Man worshiped the creature rather than the Creator.
This last week for Noah must have been fearful. Fearful because God would soon inflict a terrifying judgment upon the world— a flood through which God would blot out from the face of the land every living thing. The word "blot" signifies a total and complete removal. Everything would be wiped out (for more information on the word "blot" see Genesis 6:7).
Yet the last week for Noah must have also been hopeful. Hopeful because God, by His grace, would save him and his household. Hopeful because Noah trusted in the Lord his God— and he did according to all that the Lord had commanded him. Despite the embarrassment and ridicule Noah might have received for constructing the ark, he pressed onward; not for his own glory, but for the glory of his Creator.
