You think there is something about Noah that God liked? Then there must have been something in all of the other people on the earth that God did not like otherwise He would not have destroyed them all with a flood.
Gen 6:9 These are the generations of Noah:
Noah was a just man and perfect in his generations, and Noah walked with God.
Gen 6:22 Thus did Noah; according to all that God commanded him, so did he.
Gen 7:5 And
Noah did according unto all that the LORD commanded him.
Hebrews 11:7 By faith Noah, being warned of God of things not seen as yet, moved with fear, prepared an ark to the saving of his house; by the which he condemned the world, and became heir of the righteousness which is by faith.
Noah obeyed God because Noah believed what God told him. Noah had faith.
Gen 8:20 And Noah builded an altar unto the LORD; and took of every clean beast, and of every clean fowl, and offered burnt offerings on the altar.
Noah worshipped God. (I'm assuming this is not the first time Noah worshipped God.)
Eze 14:14 Though these three men, Noah, Daniel, and Job, were in it, they should deliver but their own souls by
their righteousness, saith the Lord GOD.
Noah did what was right in the sight of the Lord.
2 Peter 2:5 And spared not the old world, but saved Noah the eighth person,
a preacher of righteousness, bringing in the flood upon the world of the ungodly;
Noah not only did what was right, but he taught others the right way of the Lord.
