Jesus uses an illustration in Matthew 5:29-30 to show you how bad Hell really is.
29 If your right eye causes you to stumble, gouge it out and throw it away. It is better for you to lose one part of your body than for your whole body to be thrown into hell. 30 And if your right hand causes you to stumble, cut it off and throw it away. It is better for you to lose one part of your body than for your whole body to go into hell.
Jesus is making a point that Hell is so bad it would be worth cutting limbs and losing your sight to avoid it. Fortunately for us salvation is a free gift from God if we will believe in Jesus and ask Him for forgiveness.
