"His storehouse is not composed just of goods but also of time, talents, skills, and our divine nature."
Elder D. Todd Christofferson, Reflections on a Consecrated Life, October 2010 General Conference
“To consecrate is to set apart or dedicate something as sacred, devoted to holy purposes. True success in this life comes in consecrating our lives—that is, our time and choices—to God’s purposes (see John 17:1, 4; D&C 19:19). In so doing, we permit Him to raise us to our highest destiny.”

Pre-existence

Jeremiah 1:5

 5 Before I formed thee in the belly I knew thee; and before thou camest forth out of the womb I sanctified thee, and I ordained thee a prophet unto the nations.

Proverbs 8:22-31

 22 The Lord possessed me in the beginning of his way, before his works of old.

 23 I was set up from everlasting, from the beginning, or ever the earth was.

 24 When there were no depths, I was brought forth; when there were no fountains abounding with water.

 25 Before the mountains were settled, before the hills was I brought forth:

 26 While as yet he had not made the earth, nor the fields, nor the highest part of the dust of the world.

 27 When he prepared the heavens, I was there: when he set a compass upon the face of the depth:

 28 When he established the clouds above: when he strengthened the fountains of the deep:

 29 When he gave to the sea his decree, that the waters should not pass his commandment: when he appointed the foundations of the earth:

 30 Then I was by him, as one brought up with him: and I was daily his delight, rejoicing always before him;

 31 Rejoicing in the habitable part of his earth; and my delights were with the sons of men.
