Not some sky daddy!

How many times I recall educated American (and European) friends protesting that while they might believe or feasibly be able to believe in God, they could never believe in a childish idea of a Bearded Sky Daddy(TM?). For some reason I’ve never found the traditionally imagery of God the Father to be revolting. Like this:

It’s the whole Trinity – Father, Son and Holy Spirit. But my question is, what advantage or appeal comes from thinking that God is a vague force of nature with no personhood, no Incarnation, no relationship to you or me? So many of God’s best qualities are qualities that manifest in the relationship of persons: love, compassion, tenderness, mercy. Even the conversation of prayer!
