Exactly; so many get it caught in their heads that being a Christian is the equivalent of being a "good person"...when in fact, by God's standard of total perfection, no one is good but Him. You've probably heard it said, "Good people go to heaven". Well, that's wrong, due to the aforementioned standard. Since every one of us have done at least 1 thing wrong in our lives, that violates complete purity, and so we need Jesus to redeem us from this. The Bible states that in addition to being our Savior, Jesus is also our intercessor, continually pleading for us before the Father's throne.
If God provided no way for fallen people to be reconciled, then we'd all be in hell by default, regardless of how "good" we are on this Earth. God knows our hearts, even better than we do. He knows what we think and feel in the deepest core of our being. What we truly believe determines who we are and how we act. So, we are given a choice: an eternity with God, or an eternity without Him. The brutally-honest truth of the matter is this: "Forgiven people go to heaven, because none are good but God." Christians are just like everyone else, with one exception: they've embraced and accepted Jesus' offering of forgiveness and salvation through repentance and faith.
