Jesus gave up everything so that we could gain it all. In 2 Corinthians 8:9 Paul says, For you know the grace of our Lord Jesus Christ, that though he was rich, yet for your sake he became poor, so that you through his poverty might become rich. Paul was not talking about monetary riches, but spiritual. He gave up His own access to God and His kingdom to sacrifice for us so that we would know eternity in Heaven with Him. Our debt for sin was paid and for that we must be thankful.
