Genesis 7:6 And Noah was six hundred years old when the flood of waters was upon the earth. 7 And Noah went in, and his sons, and his wife, and his sons' wives with him, into the ark, because of the waters of the flood.
[Patriarchs & Prophets pp 98] God commanded Noah, “Come thou and all thy house into the ark; for thee have I seen righteous before Me in this generation.” Noah's warnings had been rejected by the world, but his influence and example resulted in blessings to his family. As a reward for his faithfulness and integrity, God saved all the members of his family with him. What encouragement to parental fidelity! Mercy had ceased its pleadings for the guilty race. The beasts of the field and the birds of the air had entered the place of refuge. Noah and his household were within the ark, “and the Lord shut him in.”
A flash of dazzling light was seen, and a cloud of glory more vivid than the lightning descended from heaven and hovered before the entrance of the ark. The massive door, which it was impossible for those within to close, was slowly swung to its place by unseen hands. Noah was shut in, and the rejecters of God's mercy were shut out. The seal of Heaven was on that door; God had shut it, and God alone could open it. So when Christ shall cease His intercession for guilty men, before His coming in the clouds of heaven, the door of mercy will be shut.
Then divine grace will no longer restrain the wicked, and Satan will have full control of those who have rejected mercy. They will endeavor to destroy God's people; but as Noah was shut into the ark, so the righteous will be shielded by divine power. For seven days after Noah and his family entered the ark, there appeared no sign of the coming storm. During this period their faith was tested. It was a time of triumph to the world without.
1st Thessalonians 5:2 For yourselves know perfectly that the day of the Lord so cometh as a thief in the night. 3 For when they shall say, Peace and safety; then sudden destruction cometh upon them, as travail upon a woman with child; and they shall not escape.
May The Lord add His blessing to the study of His word. God bless!
