The context suggests that reaping in Galatians 6:9 refers to salvation. θερίζω is the lemma. This seems to be a finite verb in my opinion. However, in a commentary by John Macarthur that I read, he argued that "eternal life" in verse 8 refers to the character of eternal life, but he made no more arguments or cited anything. Is there any evidence to back this claim, or does the reaping in verse 9 refer to salvation?
