Your mistakes do not define you. Our mistakes don't define us. There's always a choice that we make to continue making the same mistake or to correct it and move on. Mistakes don't form our identity. Our identity is formed based on what we believe.
No matter far away you've gone I testify that you have not traveled beyond the reach of Divine Love. It is not possible for you to sink lower than the infinite Light of Christ's Atonement shines-Jeffrey R. Holland
