'Lacking' in the Bible

And I rejoice at the coming of Stephanas and Fortunatus and Achaicus: for that which was lacking on your part they supplied.

because for the work of Christ he came nigh unto death, hazarding his life to supply that which was lacking in your service toward me.

Now I rejoice in my sufferings for your sake, and fill up on my part that which is lacking of the afflictions of Christ in my flesh for his body's sake, which is the church;

night and day praying exceedingly that we may see your face, and may perfect that which is lacking in your faith?

And let patience have its perfect work, that ye may be perfect and entire, lacking in nothing.
