11. Explain how Jesus’ sacrifice can greatly benefit us.

¹¹ The ransom also opened the way for us to receive other benefits, even now. For example, although we are sinners, Jesus’ sacrifice makes possible our having a clean conscience because of forgiveness of sin. This is far more than was ever achieved for the Israelites by the animal sacrifices that the Mosaic Law required. (Acts 13:38, 39; Hebrews 9:13, 14; 10:22) However, having such forgiveness requires that we honestly recognize how much we need Christ’s sacrifice: “If we make the statement: ‘We have no sin,’ we are misleading ourselves and the truth is not in us. If we confess our sins, he is faithful and righteous so as to forgive us our sins and to cleanse us from all unrighteousness.”​—1 John 1:8, 9.

13. If we realize that we have committed a sin, what should we do about it, and why?

¹³ Even after this, of course, sinful traits will show themselves. What then? The apostle John said: “I am writing you these things that you may not commit a sin. And yet, if anyone does commit a sin, we have a helper with the Father, Jesus Christ, a righteous one. And he is a propitiatory sacrifice for our sins.” (1 John 2:1, 2)
