None are Forbidden

Often, when we mess up, we feel inadequate. We may feel that Heavenly Father no longer wants to talk with us, because we don't feel worthy. In this negative frame of mind, it can become easy to spiral downward, and do worse and worse.
But our Heavenly Father just wants us to change. He won't condemn the sincere efforts of His children to become better.
Jesus Christ suffered immensely for us. He suffered so that we can have mercy when we repent and have faith in Him. He didn't go through all that so that He could then abandon us when we sin.
His hand is always outstretched.
It makes no difference where we have been. We can choose today to change our direction. And, in time, we will find that we have entered into His rest.

I know that this is true, because I have made many mistakes.
I have felt the guilt of those mistakes. I have also repented, and felt of the incredible love that Christ and my Father have for me. Even when I've fallen into a cycle of sin, He was always there to help me out each time I tried again to move on.
He will ever be there, waiting.

 "He doeth not anything save it be for the benefit of the world; for he loveth the world, even that he layeth down his own life that he may draw all men unto him. Wherefore, he commandeth none that they shall not partake of his salvation.

Behold, doth he cry unto any, saying: Depart from me? Behold, I say unto you, Nay; but he saith: Come unto me all ye ends of the earth, buy milk and honey, without money and without price.

Behold, hath he commanded any that they should depart out of the synagogues, or out of the houses of worship? Behold, I say unto you, Nay.

Hath he commanded any that they should not partake of his salvation? Behold I say unto you, Nay; but he hath given it free for all men; and he hath commanded his people that they should persuade all men to repentance.

Behold, hath the Lord commanded any that they should not partake of his goodness? Behold I say unto you, Nay; but all men are privileged the one like unto the other, and none are forbidden." 2Nephi 26:24-28

I am a witness that He lives, and that He loves us.
