We're human; we fail. It's inevitable. But it's how we respond to failure that truly makes a difference, especially when it comes to sexual sin. Sexual sin creates shame in our conscious that takes hold unlike any other. It's important to respond like David does in Psalm 51: He acknowledges his sin fully, asks God to restore the joy of salvation, and allows God to use his story to teach others and bring them back to God. God loves us no matter our past, present, or future - Christ died for us already knowing all of that! Don't be ashamed of your story; share it to teach others that they can have a story of God's love too.
