'Sin' in the Bible

Be angry [at sin—at immorality, at injustice, at ungodly behavior], yet do not sin; do not let your anger [cause you shame, nor allow it to] last until the sun goes down.

And do not grieve the Holy Spirit of God [but seek to please Him], by whom you were sealed and marked [branded as God’s own] for the day of redemption [the final deliverance from the consequences of sin].
