Come as you are is a good song by Nirvana, a band from the early 1990's. It always reminded me of Just as I am, a Christian song about coming to God no matter what you've been through or what you've done.
You really do not get cleaned up before going to God, you go to God and then get cleaned up. You come as you are. David Crowder, a Christian artist, recently released another version of Come as You Are and it is much different from Nirvana.
Below are the lyrics. Never forget that you are never too far to turn back.
