Because Jesus has come, because He has taken on flesh to set us free, because there is now no condemnation for those who are in Him, and because He now sits at the right hand of the Father to dispense all His grace and glory upon those who would believe and ask, our present life in Him is as rich as we would have it be. Any sense of lack is simply you and I not living up to our heavenly privileges.
There is more for us. And it's all to be found in Him. Right now. Today.
