1 Corinthians 9: 24* Do you not know that the runners in the stadium all run in the race, but only one wins the prize? Run so as to win.p 25Every athlete exercises discipline in every way. They do it to win a perishable crown, but we an imperishable one.q 26Thus I do not run aimlessly; I do not fight as if I were shadowboxing. 27No, I drive my body and train it, for fear that, after having preached to others, I myself should be disqualified.*
What does Paul talk about here, if not works? This theme runs through his letters. You must first believe in God, then you must do over the long run. Salvation is not a one time thing - it is where you must be at the end of your life.
Then said they unto him, What shall we do, that we might work the works of God? Jesus answered and said unto them, This is the work of God, that ye believe on him whom he hath sent. John 6:28-29
