Do we need to pray "in Jesus name". Do we need an internmediary for prayer.?

I once had a Roman catholic friend explain why they pray through intermediators. She likened it to taking a bouquet of flowers to someone. We would not just shove them in a vase but we would arrange them orderly and attractively to give to the person. She said prayers were the same. They would be arranged orderly and attractively for God.

Interesting - what?

What so you think?
