In the New Testament we get another savior, Jesus. But we cannot know if he too is God. This information is hidden behind ambiguous verses on purpose, because we are not supposed to know. Jesus told us himself in Luke 10:22 that no one knows who the Son is except the Father. So we should not be proud and think we know.
But it should not bother us that we don't know, this issue is not important for salvation. Some claim it is, but we should follow only biblical requirements for salvation and not add to them.
