'Lacking' in the Bible

Jesus said, “Are you still lacking in understanding also?

The young man *said to Him, “All these things I have kept; what am I still lacking?”

And He *said to them, “Are you so lacking in understanding also? Do you not understand that whatever goes into the man from outside cannot defile him,

so that you are not lacking in any gift, awaiting eagerly the revelation of our Lord Jesus Christ,

Now I rejoice in my sufferings for your sake, and in my flesh I do my share on behalf of His body, which is the church, in filling up what is lacking in Christ’s afflictions.

as we night and day keep praying most earnestly that we may see your face, and may complete what is lacking in your faith?

Diligently help Zenas the lawyer and Apollos on their way so that nothing is lacking for them.

And let endurance have its perfect result, so that you may be perfect and complete, lacking in nothing.
