You need some basic theology lessons.
Though I'm not a Southern Baptist, I can refer you to the Rev. Charles Stanley.
You are not forgiven of your sins, you are forgiven of your sins that you ask God to forgive you for. You must ask.
A murderer, though he were "saved" earlier, by declaration in a church or even in solitude, who dies unrepentant will not be close to God in the afterlife. Of this I am sure.
Every believer at the moment of belief has returned to God with intent, i.e. has repented.
Once He then bestows eternal life, even He is unable to remove it through faith in Christ.
If you drive 22 mph in a 20 mph school zone, but are unrepentant of that excessive speed drive, would you also 'lose' your salvation?
