You are righteous in God's eyes.
You can not be any more righteous.
You can't write a check to be righteous. You can't read the bible in one year to be righteous. You can't pray an hour a day to be righteous. The only way to be righteous is through faith in the One that gives you righteousness, and if you try to get righteousness any other way than by receiving it as a free gift, it becomes works, and you've contaminated it, and it won't work. You become double-minded, and a double-minded man is unstable in all his ways.
You cannot live in the blessings of the second Adam, when you have a "first Adam" perspective. You simply cannot live out the new covenant with an old covenant mindset. That’s why Jesus said you can't put new wine in an old wineskin. You are righteous - not because of you - but because of Him.
If you can believe that and settle that, and know that you'll never lose your righteousness, but simply rest in the righteousness that Christ has provided for you, you'll begin to experience the blessings He has for you. Your life will begin to bear the fruit of righteousness.
On the other hand, if you think for one minute that you can lose it, then your righteousness will all be based on you and your ability to always make the right decisions. Then you'll do everything you can to try to get your righteousness back, and you'll end up in the same works-based mindset that caused the apostle Paul to write, "You foolish Galatians! Who has bewitched you?" It is a subtle, but vitally important shift in mindset to go from, "I behave righteously in order to remain righteous," to "I behave righteously because I am righteous."
The former is a curse and a bondage of never-ending works.
The latter is blessing and freedom, resting in Christ.
