I have been fascinated for as long as I can remember by the general Christian practice of praying to Jesus and closing by saying simply, "Amen." The Bible is as clear about prayer as about anything else included in it. Christians are taught to pray to the Father in Christ’s name:
(John 15: 16) - "Ye have not chosen me, but I have chosen you, and ordained you, that ye should go and bring forth fruit, and that your fruit should remain: that whatsoever ye shall ask of the Father in my name, he may give it you."
(John 16: 23-24) - "And in that day ye shall ask me nothing. Verily, verily, I say unto you, Whatsoever ye shall ask the Father in my name, he will give it you. Hitherto have ye asked nothing in my name: ask, and ye shall receive, that your joy may be full."
There is a HUGE difference between feeling a personal connection to / relationship with Jesus as your Savior and Redeemer and using that connection / relationship to place Jesus between you and the Father in prayer - to allow Him to be your mediator with the Father. It’s hard to read the Bible in its entirety and come to the conclusion that we should pray to Jesus. Rather, we are to pray in His name ("through Him") - invoking His grace in allowing us to speak directly with the Father.
