'Completion' in the Bible
While Jesus was seated on the Mount of Olives, the disciples came to Him privately, and said, “Tell us, when will this [destruction of the temple] take place, and what will be the sign of Your coming, and of the end (completion, consummation) of the age?”
After that comes the end (completion), when He hands over the kingdom to God the Father, after He has made inoperative and abolished every ruler and every authority and power.
So now finish this, so that your eagerness in desiring it may be equaled by your completion of it, according to your ability.
I am convinced and confident of this very thing, that He who has begun a good work in you will [continue to] perfect and complete it until the day of Christ Jesus [the time of His return].
No one has seen God at any time. But if we love one another [with unselfish concern], God abides in us, and His love [the love that is His essence abides in us and] is completed and perfected in us.
In this [union and fellowship with Him], love is completed and perfected with us, so that we may have confidence in the day of judgment [with assurance and boldness to face Him]; because as He is, so are we in this world.
