Paul changed his purpose for the present. Being saved by faith may give the impression that there is no motivation for conduct and works. Paul dissipates that notion in this section. He exhibits an effort and energy derived from the Holy Spirit, which is far greater than any legal effort. Under the Law, he would go to Damascus to stamp out the followers of Christ. Under the grace-faith system, he will go to the end of the earth to make followers of Christ and to witness for Him. At the end of his life, his ambition is still to know Christ — His person, the power of His resurrection, the fellowship of His sufferings. To know Christ and His work of redemption will engage our attention for eternity. Paul affirms that he will have a part in the rapture, with great joy. Paul does not expect to attain perfection in this life. The knowledge that he will not attain perfection here does not deter him from moving in that direction. This is the prize for Christian living. Paul’s future is so absorbed by Christ that it motivates everything he says and does in the present. He likens himself to a track star running for a prize. His prize is not some earthly award, but Christ Himself. There are some who profess Christ yet contradict all of this by their lives.
