Yeah, I still call God Jehovah when I pray. However, I have discarded many of the Bible's notions of who He is and what He is up to, in fact, He isn't a He - he's a spirit, ergo, no gender, but I refer to him in the masculine because that's who I can identify with.
A great deal of my current theology is based on personal experience, studying creation, and social philosophy.
I don't pray through Jesus anymore. I don't believe in original sin anymore, ergo, no need for a ransom or a mediator - in fact I strongly doubt the historicity of the Bible. However, many of the concepts Jesus embodied (literally or not) are useful in day to day living. Reliance on God, abandonment of materialism, following where God leads, use of God-given talents to the maximum, hope in God's eventual salvation of all mankind, belief in justice and a continuance of life.
The name works for me.
