In life we often take up a lot of time, talent, stress and daily worries thinking about money. Our lives revolve around money: how to save money, how to earn more, what to spend it on, what is has been spent on, how much we owe, and how much is owed to us. It seems, despite the lyrics of classic oldies, nothing in life is free.
In 2 Nephi 9:50, Nephi's younger brother Jacob tells us the most important thing in our pre-mortal life, in this life, and the life to come is absolutely free. Salvation and the Gospel of Jesus Christ and the resulting blessings cost us nothing, except devotion and a broken heart and contrite spirit. Jacob says "Come, my brethren, every one that thirsteth, come ye to the waters; and he that hath no money, come buy and eat; yea, come buy wine and milk without money and without price."
Milk and honey, a biblical culinary staple, represents ease of life and richness in the land. So while we might not think of milk and honey as something signifying our riches, in biblical times that meant their life was made, basically. So from that we can learn that the blessings of the gospel are ease of life, and richness of the land. Once we've become converted and follow Christ our lives become infinitely better, maybe not perfection how we think of it, but perfection in God's eyes, and exactly what He has planned for us.
So, while everything in this life may seem to cost money and not be of value to us, especially eternally, the Gospel of Jesus Christ costs us nothing, and is what we should be concentrating on in this life. Eternal life, and living in the presence of God and Jesus Christ, should be our focus here in this mortal life.
