Each Christian receives eternal life when faith takes hold of his or her life. But no matter when it happens, every Christian has eternal life from the moment it happens. Eternal life makes a difference in our lives even before death. 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.
