My son, give ear to my words, for I say unto you, even as I said unto Helaman, that inasmuch as ye shall keep the commandments of God ye shall prosper in the land; and inasmuch as ye will not keep the commandments of God ye shall be cast off from his presence. And now, my son, I trust that I shall have great joy in you, because of your steadiness and your faithfulness unto God; for as you have commenced in your youth to look to the Lord your God, even so I hope that you will continue in keeping his commandments; for blessed is he that endureth to the end.
If we follow the commandments of God we will recive his blessings. This does not mean that we will be rich or have lots of possessions, but it means that we will be prosperous. If we fall away from God, we will lose our prosperity and life will become harder to go though.
