The Gospel doesn't tell guilty people to try harder—it tells them where to find rest.
Not rest you'll experience someday after you die, but rest that meets you right here in the messiness of life. Maybe you've been managing your guilt by staying busy, numbing out, or beating yourself up. But grace offers a better way. Romans 5:2 reminds us we "have gained access by faith into this grace in which we now stand." Stand in it today. Bring your guilt, your shame, your regrets to Jesus and let Him carry what you were never meant to bear. Continuing to carry guilt doesn't make you more humble—it diminishes the sufficiency of the cross.
Jesus said, "It is finished." Believe Him. Live free.
