JMNT(i)
13 Brothers (= Fellow believers; = [My] family)! I am not [other MSS: not yet] calculating (logically considering; reckoning) myself to have taken it down by hand (seized, grasped or gotten hold of it in order to have it), yet [there is] one thing: habitually forgetting, on the one hand, the things behind (or: in the back), and on the other hand constantly reaching and stretching myself out upon the things in front (or: ahead),
14 I am continuously pressing forward, pursuing down toward [the; or: an] object in view (a mark on which the eye is fixed): into the awarded contest prize of God's (or: the award which is God's) invitation to an above place (or: an upward calling having the source from, with qualities and characteristics of, God) within the midst of and in union with Christ Jesus.
15 Therefore – as many as [are] people who are mature (ones who have reached the goal, being finished and complete) – we should constantly be of this frame of mind (have this attitude and opinion; think this way; be minding and paying attention to this). And if you folks are habitually thinking differently (are continuing differently minded; are continually having a different attitude or opinion), God will also proceed in unveiling this to you (or: uncovering and revealing, or disclosing, this in you).
16 Moreover, into that which we precede [others] (or: into what we went before in; into what we come ahead so as to arrive at; = unto whatever stage we have reached) in the very same thing [our goal is] to be habitually drawn into a straight line and consistently advance within our ranks [Aleph2 and other MSS add phrases to read as follows: Besides, into what we outstrip {others}, by the same standard (measuring rod; rule) {it is for us} to habitually advance in line (i.e., frame our conduct in an orderly routine; or: consider the elements and observe the rudimentary principles by the same standard) – to constantly be intent on and keep thinking of the same thing (or: be of the same frame of mind and attitude)].
