Let's first look at some instances in the Bible where a person tried to worship a being other than God or Jesus.  (All references are to the New International Version Bible.)

While receiving the Revelation of Jesus Christ on the Isle of Patmos, the Apostle John was apparently so overcome with thankfulness, love, and awe that he bowed down to worship an angel who was showing him this vision – on two occasions.  But each time the angel said, "Do not do it!  I am a fellow servant with you and with your brothers….  Worship God!"  – Revelation 19:10 and Revelation 22:9 

When Peter was sent to Cornelius, the first Gentile convert, Cornelius greeted Peter as he entered the house by falling in reverence at Peter's feet.  "But Peter made him get up.  'Stand up,' he said, 'I am only a man myself.'" – Acts 10:26

When Paul and Barnabas healed a crippled man in Lystra, the crowd wanted to honor them as gods.  Definitely not wanting to be associated with any pagan gods, but also refusing to accept any honor for themselves, Barnabas and Paul shouted, "Men, why are you doing this?  We too are only men…  We are bringing you good news, telling you to turn… to the living God…" – Acts 14:11-18 

So we see that the apostles and even angels made it plain that we are to only worship God.  However, God Himself does not accept sinners on their own merit.  The Jewish people were given the Law Covenant, but it was impossible for imperfect man to keep it. and they were never completely justified in God's sight.  So God sent us His Son, Jesus Christ, to die in place of Adam for us.

Jesus "humbled himself and became obedient to death – even death on a cross!  Therefore God exalted him to the highest place and gave him the name that is above every name, that at the name of Jesus every knee should bow, in heaven and on earth and under the earth, and every tongue confess that Jesus Christ is Lord, to the glory of God the Father." – Philippians 2:8-11 (Italics added) 

"Therefore he is able to save completely those who come to God through him, because he always lives to intercede for them."  Hebrews 7:25

Nowhere in the Bible are we told to pray to anyone else.

We await the time when all people will worship God and His Son, "for the earth will be full of the knowledge of the LORD as the waters cover the sea." – Isaiah 11:9;  Habakkuk 2:14

Because we have "an advocate with the Father, Jesus Christ the righteous" (I John 2:1), we do not need to, nor should we, pray to anyone but those two.
