# The crown of righteousness has been reserved for me

"God has reserved the crown of righteousness for me" 

# crown of righteousness

Just as the judge of a race gives a crown to the winner, when Paul finishes his life, God will declare that Paul is righteous.

# on that day

"on the day when the Lord comes again" or "on the day when God judges people"

# but also to all those who have loved his appearing

"but also he will give it to those who are eagerly waiting for him to return"
