For it is written, "There are none righteous, no, not one!"
Jesus said best when a man approached Him, saying, "Good Master...." Jesus replied, "Why do you call me good? There is none good, but one; the Father."
Let's take the test: Have you ever lied?
Have you ever stolen?
Have you ever used God's name in vain (as a cuss word)?
Have you ever lusted in your heart (Jesus said to lust for another is adultery)?
Have you made a God to suit yourself (idolatry)?
Personally, I have broken almost every one of the Ten Commadnments, so to say I am a good person is to proclaim self-righteousness. I may seem a better person than some in the eyes of others, but God doesn't see it that way. He sees the little sin as the big sin, and the breaking of the entire law!
I am no good, yet; I am made righteous through the Blood of Christ, that God may now look upon me and see only His Son, the only one that was good in the eyes of God, 100% sin-free!!
