John 14:6-7

Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me. If ye had known me, ye should have known my Father also: and from henceforth ye know him, and have seen him.

Only through Christ can we know the Father. But through Christ we can have a great relationship with the Father.  God is a loving God who wants to be a part of our lives, and be believing on Christ we can allow that to happen.
