1In the past God spoke to our forefathers through the prophets at many times and in various ways, 2but in these last days he has spoken to us by his Son, whom he appointed heir of all things, and through whom he made the universe. 3The Son is the radiance of God's glory and the exact representation of his being, sustaining all things by his powerful word.
Who is Jesus? this is the question and here is the beginning of the answer
'the radiance of God's glory and the exact representation of his being'
it is awesome to comprehend that he 'sustains all things by his powerful word'
that is something to pray and and reflect on.
