'Full' in the Bible

The Spirit is the guarantee [the first installment, the pledge, a foretaste] of our inheritance until the redemption of God’s own [purchased] possession [His believers], to the praise of His glory.

which is His body, the fullness of Him who fills and completes all things in all [believers].

[and He did this] to fully equip and perfect the saints (God’s people) for works of service, to build up the body of Christ [the church];

until we all reach oneness in the faith and in the knowledge of the Son of God, [growing spiritually] to become a mature believer, reaching to the measure of the fullness of Christ [manifesting His spiritual completeness and exercising our spiritual gifts in unity].

From Him the whole body [the church, in all its various parts], joined and knitted firmly together by what every joint supplies, when each part is working properly, causes the body to grow and mature, building itself up in [unselfish] love.
