We often think of righteousness as getting it right and making correct choices. And surely it includes those things. But to anyone who does not always get it right or have a perfect record of making correct choices (ahem, that's everyone by the way), righteousness seems unattainable and those who aspire to it seem "holier than thou." But we have it wrong if we think this way.
Part of getting it right - a big part - is having an awareness and desire to get it right more often. One correct choice is to be humble and always striving to improve. Righteousness includes total dependence on Jesus Christ and His atonement because you know you can't do it on your own.
Who is righteous, then? Those who are repenting.
Does repentance feel like a burden? Are you able to approach goals and changes you want to make as an opportunity for repentance? Doing so takes a humble heart. When we take our broken heart and contrite spirit to the Savior, He gives us access to the power of the atonement!
Dieter F. Uchtdorf taught, "True repentance is about transformation, not torture or torment." And Howard W. Hunter enlightens us further, stating, "The great miracle of the church and kingdom of God in our day and in our time is the transformation of the human soul."
