'Lack' in the Bible

He wondered at their unbelief.And He was going around in the villages teaching.

acts of greed and covetousness, wickedness, deceit, unrestrained conduct, envy and jealousy, slander and profanity, arrogance and self-righteousness and foolishness (poor judgment).

Looking at him, Jesus felt a love (high regard, compassion) for him, and He said to him, “You lack one thing: go and sell all your property and give [the money] to the poor, and you will have [abundant] treasure in heaven; and come, follow Me [becoming My disciple, believing and trusting in Me and walking the same path of life that I walk].”

Later, Jesus appeared to the eleven [disciples] themselves as they were reclining at the table; and He called them to account for their unbelief and hardness of heart, because they had not believed those who had seen Him after He had risen [from death].
