Forgiveness.

Ephesians 1:7

⁷ In him we have redemption through his blood, the forgiveness of sins, in accordance with the riches of God’s grace

There's no such thing as 'too big of a sin'. God views all sins equally. From stealing to lying. I used to think that God wasn't able to forgive my sins because it was such a bad thing to do. I didn't know how to get rid of that sin. Then i realized that God forgives each and every one of us no matter what. He does it through his grace and mercy and although we don't deserve it he still offers it to us. It's up to us, whether or not we want to repent. God's love is so amazing. His love for us is so abundant that he was willing to give us his one and only son to die on the cross for our sins.

He's a very forgiving God because he cares for us and he wants us to go to Heaven to spend eternity with him.
