God will take care of those who have faith and will follow Him. A message so important it was written twice. 

Luke 12: 27-28

27 Consider the lilies how they grow: they toil not, they spin not; and yet I say unto you, that Solomon in all his glory was not arrayed like one of these.

 28 If then God so clothe the grass, which is to day in the field, and to morrow is cast into the oven; how much more will he clothe you, O ye of little faith?

3 Nephi 13: 28-30

 28 ....Consider the lilies of the field how they grow; they toil not, neither do they spin;

 29 And yet I say unto you, that even Solomon, in all his glory, was not arrayed like one of these.

 30 Wherefore, if God so clothe the grass of the field, which today is, and tomorrow is cast into the oven, even so will he clothe you, if ye are not of little faith.
