For we know that when this tent we live in - our body here on earth - is torn down, God will have a house in heaven for us to live in, a home he himself has made, which will last forever. 1
References for 2 Corinthians 5:1
And now we sigh, so great is our desire that our home which comes from heaven should be put on over us;
by being clothed with it we shall not be without a body.
While we live in this earthly tent, we groan with a feeling of oppression; it is not that we want to get rid of our earthly body, but that we want to have the heavenly one put on over us, so that what is mortal will be transformed by life.
God is the one who has prepared us for this change, and he gave us his Spirit as the guarantee of all that he has in store for us.
So we are always full of courage. We know that as long as we are at home in the body we are away from the Lord's home.
