Attain means,
Arrive at, come to, reach (literally or figuratively). ('Attained' means,
reached, came to, arrived at.)...That I may know Him, and the power of His resurrection, and the fellowship of His sufferings, being made conformable unto His death; if by any means I might attain unto the resurrection of the dead. Not as though I had already attained, either were already perfect: but I follow after, if that I may apprehend that for which also I am apprehended of Christ Jesus. Phillipians 3:10-12
