Preaching is not done well in many churches. Well- educated preachers in some mainline churches fill their sermons with theological abstractions. Pentecostal preaching is often a loud reiteration of exhortations lacking theological substance. And other churches which may have better preaching often don't know how to be 'lost in wonder, love and praise' in their worship. The preacher stands between heaven and earth, speaking for God to us, and strengthening our faith, hope and love.
Conversation is two-way dialogue.
So is worship. When God speaks, we respond. God tells us he is not pleased with worship that's just words or formulas, and does not lead to a changed life. Indeed if worship does not change us it is not true worship. Perhaps once a month have a special offering for the poor.
