John Piper, in his book Seeing and Savoring Jesus Christ, writes,

“The Father has eternally enjoyed ‘the radiance of His glory and the exact representation of His nature’ (Heb. 1:3) in the Person of his Son.  Seeing and savoring this glory is the goal of our salvation. ‘Father, I desire that they also, whom You have given Me, be with Me where I am, so that they may see My glory which You have given Me’ (John 17:24). To feast on this forever is the aim of our being created and our being redeemed.”  HT :: OFI
