Q3. (Romans 5:6, 8) Why is it so important to embrace the truth that "Christ died for the ungodly" (5:6), that "Christ died for sinners" (5:8)? According to 5:8, did Christ die for us at our best or at our worst? How does this give us assurance against the devil's lies about us being too bad to forgive?
God died for us at our worst.
It gives us assurance because since he freely gave is life for our salvation before we even accepted his gift. Once we accept his gift Jesus will forgive our sins no matter how bad we think they are, they are no match for God.
