Who is Jesus? Is the God of Jehovah's Witnesses his Father?

He is the image of the invisible God, for no one has seen God but the only begotten God has revealed Him. Colossians 1:15; John 1:18

For I did not come to judge the world, but to save it. John 12:47

Come to me, all you who are weary and burdened, and I will give you rest. Matthew 11:28

“Drink, for this is my blood, which is poured out for many for the forgiveness of sins." Matthew 26:28

Does the Jehovah that Jehovah's Witnesses worship give rest? Does he save the world, or judge it? Is he humble enough to wash his followers feet?
