Grace is still found in a wicked world.
The whole world was corrupt, but one man found grace.
Genesis 6:8 (KJV): But Noah found grace in the eyes of the LORD.
Noah was not saved because he was better by nature. All have sinned.
Romans 3:23 (KJV): For all have sinned, and come short of the glory of God;
Grace is God's gift, and it comes through faith.
Ephesians 2:8 (KJV): For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:
God's grace reached Noah's whole house, not only Noah.
Genesis 6:18 (KJV): But with thee will I establish my covenant; and thou shalt come into the ark, thou, and thy sons, and thy wife, and thy sons' wives with thee.
