You were dead because of your sins and because your sinful nature was not yet cut away. Then God made you alive with Christ, for he forgave all our sins.
Do you behave like someone who has been forgiven of their sinful nature? Do you dance with joy, sing out loud, and forgive those who wrong you? These are only a few qualities of a forgiven person. If not, focus on the undeserved grace you’ve been given, then you can experience the joy. God has wiped away our sins, so let’s act like it.
