'Fullness' in the Bible

for the administration of the fullness of times, to bring together all things in Christ, the things in the heavens and the things on the earth, in him

which is his body, the fullness of the one who fills all [things] in every [way].

and to know the love of Christ that surpasses knowledge, in order that you may be filled up to all the fullness of God.

until we all reach the unity of the faith and the knowledge of the Son of God, to a mature man, to a measure of the maturity of the fullness of Christ,
