Loving another person is the closest any of us will ever get to understanding the world of original design. Being loved by another person is the closest any of us will ever get to understanding Jesus. Having a rock solid confidence in the love of another is the closest we will get, while on earth, to finally being with God in glory; His child. No wonder love is awesome!
On earth, there are holes in souls that cannot be fully filled until God and His original design is restored in all our intended glory with Him in Heaven and on the new Heaven on earth. However, fruit is the natural result of relationship now, with God and others. The command, then, to love one another, given to us by Jesus, provides us with the closest to the sublime, attainable at this present time. The rest is mumps and measles. It really is about love.
