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.
