Jesus is God.
You may ask, how can Jesus be God and still pray to His Father in Heaven? This is a valid question.
Consider this:- a river rises in the mountains and flows towards the sea; lets call the river the Tugela. After a distance the Klip river flows into it, and a little further on the Buffalo river flows into it. Eventually the Tugela flows into the sea. But where are the Klip and the Buffalo rivers? They are in the Tugela.
But we don't say three rivers flow into the sea, we talk of ONE river.
In the same way God is ONE God, but He comprises of more than one part. Jesus is God, like the Buffalo river is the Tugela where it goes into the sea.
If you take a bucket of water out of the Tugela, you are going to say "This is Tugela water." Jesus was taken out of God the Father for awhile, but He was fully God, and is fully God now.
The Trinity, as God is referred to, is often spoken of as 3 persons, but in my opinion He is One God, with 3 facets or dimensions, each with His own personality. We humans were created in the likeness of God, but it is in a much simpler form than that of God.
Explaining this is like trying to explain to a deep sea fish what riding a bicycle is like: it doesn't know what a bicycle is, it doesn't know what legs are, or air, or a road. It is a dimension that it cannot even imagine.
And it is like that with our perception of God. We try to squash Him into a box like He's some sort of supernatural human, when in fact He is unimaginally superior to our intellects and imagination.
And yet He loves us, and was willing to die, Himself, for our sins, so that we could be declared not guilty, and become His friends. Amazing love!
