It radically changes our perspective about what happens in the here and now. Eternal life allows the Christian to turn the temptation of sin into a blessing. Pride makes it all the more humble. Laziness makes it all the more industrious. Greed makes it all the more generous.
Anger makes it all the more gentle.
In this way temptation turns out to be a great blessing. This happens because Christians see themselves as part of God's eternal kingdom which includes the here and now. God's eternal reign is not waiting on a someday, bye and bye. God's kingdom is already breaking into our world. When we have faith in what Jesus did for us on the cross, we are given a new relationship with God.
