Not that I have already attained, or am already perfected

Philippians 3:12
Not that I have already attained, or am already perfected; but I press on, that I may lay hold of that for which Christ Jesus has also laid hold of me. 

We have heard about the process of sanctification which we are suppose to go through when we belong to Christ and we mature. Sanctification itself is not the end goal, perhaps it can be thought of as a guide as to how we are walking with God - whether we are maturing or drifting. The end goal then, as always has been, is to be back in a relationship with God. It is about truly recognizing God as our Father and being restored to Him.

Not that I have already attained, or am already perfected

Philippians 3:12
Not that I have already attained, or am already perfected; but I press on, that I may lay hold of that for which Christ Jesus has also laid hold of me. 

Paul started this verse recognizing the reality that we will never be perfect in this life, although we are in the process of sanctification. It is humbling and it is the reality, that God does not call on perfect people to do His work. God is using us the way we are and it is God who calls us for His work. Our own abilities may or may not be a factor, after all it is God who gives us all of our abilities. But we are never qualified in ourselves, for it is God who chooses any of us to do His work for His glory, not ours.
