In Genesis 7:1 it says, “Then the LORD said to Noah, “Come into the ark, you and all your household, because I have seen that you are righteous before Me in this generation.”
Noah’s family was saved because he was righteous. It was not because his sons were righteous or his daughter in laws. The family was saved because Noah stayed faithful to God.
As a parent we can take heart in knowing that as long as we are staying faithful to the Lord’s teachings, our family has that protection. This gives parents all the more reason to live as Christ and be true Christ followers.
Just as Cain inherited the nature of sin from Adam, so do our children inherit sin. This is why we have to teach our children God’s love, God’s grace, and God’s mercy. God overcomes the sinful nature of man, but that can only happen if we allow it.
