Philippians 3:12-16

Not that I have already obtained, or am already made perfect: but I press on, if so be that I may apprehend that for which also I was apprehended by Christ Jesus. Brethren, I count not myself yet to have apprehended: but one thing I do, forgetting the things which are behind, and stretching forward to the things which are before, I press on toward the goal unto the prize of the high calling of God in Christ Jesus. Let us therefore, as many as be perfect, be thus minded: and if in anything ye are otherwise minded, even this shall God reveal unto you: only, whereunto we have already attained, by that same rule let us walk.
