Regardless, this is showing God's love for his people. That even when they accidentally mess up, he offers them grace. God still does this today. Sometimes it is hard for people to understand His ability to forgive, and think "I've done this. How could God forgive me?" But he does.
Lord, I thank you for your love and grace, that you continuously offer it even though we may stumble and fall. Please continue to help me grow so I may see the mistakes before I make them. Amen.
