It is not possible to make real change all by ourselves. Our own willpower and our own good intentions are not enough. When we make mistakes or choose poorly, we must have the help of our Savior to get back on track. We partake of the sacrament week after week to show our faith in His power to change us. We confess our sins and promise to forsake them.
When our best efforts are not quite enough, it is through His grace that we receive the strength to keep trying. The Lord says: "If men come unto me I will show unto them their weakness. I give unto men weakness that they may be humble; and my grace is sufficient for all men that humble themselves before me; for if they humble themselves before me, and have faith in me, then will I make weak things become strong unto them."
