What do you consent to?

In Acts 8:1, it states "Now Saul was consenting to his death." I often see that we as Christians contribute to the spiritual deaths of people because we do not give them the the cure, the Lord Jesus. I have to admit, I am not a gifted speaker so I don't always feel comfortable talking to people about spiritual things. But we must ask God to grant us boldness to share the truth about our sinful nature and why we need Jesus. In what ways would you suggest we can share Christ with a lost and dying world?
