Fear not, you are numbered

"Fear not, little children, for you are mine, and I have overcome the world, and you are of them that my Father hath given me; 

And none of them that my Father hath given me shall be lost." -D&C 50:41-42

"Ye are they whom my Father hath given me; ye are my friends;" -D&C 84:63

And the Father and I are one.  I am in the Father and the Father in me; and inasmuch as ye have received me, ye are in me and I in you." -D&C 50:43
