Romans 8:23-25

But it is not just creation alone which groans; we who have the Spirit as the first of God's gifts also groan within ourselves as we wait for God to make us his children and set our whole being free. For it was by hope that we were saved; but if we see what we hope for, then it is not really hope. For who of us hopes for something we see? But if we hope for what we do not see, we wait for it with patience.
