New International Version (NIV)
However, I consider my life worth nothing to me; my only aim is to finish the race and complete the task the Lord Jesus has given me—the task of testifying to the good news of God’s grace.

English Standard Version (ESV)
But I do not account my life of any value nor as precious to myself, if only I may finish my course and the ministry that I received from the Lord Jesus, to testify to the gospel of the grace of God.

King James Version (KJV)
But none of these things move me, neither count I my life dear unto myself, so that I might finish my course with joy, and the ministry, which I have received of the Lord Jesus, to testify the gospel of the grace of God.
