Basil of Caesarea

Just as … great distances make the perception of visible objects dim, but a nearer approach offers a clear knowledge of the objects seen, so also in the case of objects of contemplation in the mind, he who has not drawn near to God is not able to see his works with the pure eyes of his mind. Therefore, "Come," first approach, then see the works of the Lord, which are prodigious and admirable.… He who has heard the call and has approached and cleaves to the One commanding will see him who through the cross made all things peaceful "whether on the earth or in the heavens."
