Lord Vishnu is the one who was never born yet he is born in everything, Vishnu is a manifestation of the Parabrahma( the formless one, Ultimate Brahman) along with Shiva and Brahma.
Vishnu is the great pervader, He is the internal controller who pervades the whole universe according to Rig Veda He is the supreme cosmic, eternal,spaceless, timeless Brahman who supports the cosmic manifestation in space and time. He is the Universal spirit who ensouls the cosmic forms and movements, As Paramesvara he presides over the individual souls and as Purushottam he fills our being and illumines our understanding and sets in motion our hidden springs.
Vishnu's role among the Trinity is to preserve the universe and at times take incarnations when dharma goes down at it's lowest.
