FOR ALL HAVE SINNED AND FALLEN SHORT OF THE GLORY OF GOD! We have all sinned but God will always forgive you no matter what you did. From lying to your sister to murdering, God will forgive you!
That doesn't mean that God is okay with you lying or murdering someone, but He will forgive you if you give Him your time and commitment to follow after Him.
Bonus: It feels REALLY good to have your sins forgiven by the Lord Almighty!
