We try again and again to be so good because we think that we have to be because we’re Christians. Doing good things isn’t wrong but it will NOT save us. Christ saved us when He died on the cross years and years before we were born so your behavior didn’t cause it or hamper it.

So if you have accepted Christ HE has you covered .

Rom 5:8
8 But God demonstrates his own love for us in this: While we were still sinners , Christ died for us.
NIV
