The city has no need of sun or moon to shine on it.Revelation 21:23
Further on, in the better world, the residents are not dependent upon creature comforts. They do not need new clothes; their white robes never wear out, nor do they become soiled or tattered. They don't need medicine to heal diseases, for no one will ever say, "I am sick." They do not need sleep to restore their strength-they do not rest by day or night as they praise God in His temple. They do not need social relationships to grant comfort, and whatever happiness they may derive from association with their fellows is not essential to their bliss, for the presence of Jesus is enough for their largest desires. They do not need teachers there; they doubtless commune with one another concerning the things of God, but they do not need to be instructed; they will all be taught of the Lord.
We receive donations at the King's gate, but they feast at the table itself. Here we lean upon the friendly arm, but there they lean upon the Beloved and upon Him alone. Here we need the help of our companions, but there they find all they need in Christ Jesus. Here we look to the food that perishes and to the clothing that decays before the moth, but there they find everything in God. We use the bucket to fetch water from the well, but there they drink from the fountainhead and put their lips down to the living water. Now the angels bring us blessings, but then we will not need messengers from heaven. They do not need angels there to bring their love-notes from God because they see Him face to face. What a blessed time it will be when having moved beyond every secondary cause we rest upon the bare arm of God! What a glorious hour when God, and not His creatures-the Lord, and not His works-will be our daily joy! Our souls will then have attained the perfection of bliss.
