“…… that I may know him, and the power of his resurrection, and the fellowship of his sufferings, becoming conformed unto his death;
“…..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 are perfect, be thus minded: and if in anything ye are otherwise minded, this also shall God reveal unto you.” Phil 3
“This one thing I do”. In all the ways, in all the aspects, in all the phases, in all the many-sided occupations “that I may know him”; that I may know Him along this line, down this way, through this avenue, through all the avenues and ways of life, I am set to make one thing govern everything: to know Him; “for the excellency (that does not mean only the splendor, but the transcendence) of the knowledge of Christ Jesus my Lord”. Concentration of purpose – “this one thing”, an undistracted life, an undivided interest, everything gathered and focused on one thing; whatever comes must in some way be made to serve this end: my fuller knowledge of the Lord. It is the only way to economize in life; otherwise you have a lot of wasted things that count for nothing. Paul would look at everything and ask, ‘What has this in it of potentiality to bring me into some further and fuller knowledge of Christ Jesus my Lord?’ Through sufferings, “the fellowship of his sufferings”; through conformity to His death, but always the cry, “that I may know him”. This is concentration of purpose.
Oh, there is the fullness. It is there, it is ours, but we need a spirit to lay hold, to persist; this spirit “Not that I have already obtained, or am already made perfect.” That spirit alone will bring us into the experience of what is ours. It is a terrible thing to have been heir to a very great deal and yet never to have known what was ours. The Spirit of God would make us know.
