Perfection - Philippians 1:6

Philippians 1:6 ESV 

And I am sure of this, that he who began a good work in you will bring it to completion at the day of Jesus Christ.

Philippians 3:12

Not that I have already obtained this or am already perfect, but I press on to make it my own, because Christ Jesus has made me his own.

Hebrews 12:22-24

But you have come to Mount Zion and to the city of the living God, the heavenly Jerusalem, and to innumerable angels in festal gathering,

and to the assembly of the firstborn who are enrolled in heaven, and to God, the judge of all, and to the spirits of the righteous made perfect,

and to Jesus, the mediator of a new covenant, and to the sprinkled blood that speaks a better word than the blood of Abel.

Obtaining perfection in our body is not possible until Christ returns and clothes us in new bodies. If we are in the body of Christ, we have obtained perfect righteousness, for we are hidden in His perfect righteousness. 

We are perfect according to God's plan and will be perfected upon His return. 

It is the perfect life.
