If God hasn't forgiven you, you're not a Christian, period.

"I have great relationship with God...I like to be good. I don't like to have to ask for forgiveness. And I am good. I don't do a lot of things that are bad. I try to do nothing that is bad...I think if I do something wrong, I think, I just try and make it right. I don't bring God into that picture. I don't."

The above quote is typical of a post-modern, "I'm good enough for God" attitude, one sadly often acquiesced to in some Christian circles, though they certainly should know better.  What would Paul's response be to such twisted thinking?  A few simple quotes from his letter to the Ephesians ought to illustrate it: "In him we have redemption through his blood, the forgiveness of sins, in accordance with the riches of God's grace (1:7)...As for you, you were dead in your transgressions and sins (2:1)...Like the rest, we were by nature objects of wrath.  But because of his great love for us, God, who is rich in mercy, made us alive with Christ even when we were dead in transgressions - it is by grace you have been saved. (2:3-5)...For it is by grace you have been saved, through faith - and this is not from yourselves, it is the gift of God - not by works, so that no one can boast. (2:8-9)"

We are not good enough for God on our own, never, ever does the Bible say anything of the sort, the idea is anathema to the Gospel.  We must be forgiven for our sins, period, and this only by the blood of Christ, only through faith, only by grace.  Anything less, and we remain dead in our sins, to pretend otherwise is to leave the sinner separated from God.

The initial quote is from a famous person, somebody who claims to be a Christian, who is accepted as a Christian by many people, but who most certainly is not a Christian if those words reflect his/her heart.  The true follower of Jesus Christ knows that he/she is only a sinner saved by grace, and knows that God's forgiveness means everything.
