Message 25:7

There are those that doubt the message, and are discouraged, but if they will keep the commandments of the Lord, their reward is sure. There are those that are filled with traditions of men, and are deprived of many blessings. There are those that are a law unto themselves, they have no part in this work, for the Lord will not accept of them and their works.

To fully receive the blessing of the Lord we need to follow only his commandments. We cannot pick a chose which ones we want to follow. We have to believe all the words of God. This includes the Bible, the Word of the Lord, and the Record of the Nephites. Will you believe and follow the truth or will you be left in darkness?
