Titus 3:5

He appeared - so what? Well, he saved us. I guess the first question may be about why he would save us. Paul is first clear to point out wrong reasons for his saving of us. He didn't save us because of any kind of "good works" that we did. It's not as if we were so good that we deserved being saved in any way, shape or form. His saving of us has to do with his mercy. He withholds the wrath and punishment of sin upon us. In a sense, we are saved from God because he would otherwise destroy us. He is merciful and does not give us what we rightfully deserve. It's not what we do, but it's what he does.
