What makes preaching relevant is your ability to make the message simple enough for your audience so that they can relate to them in their daily life in application.

Not using words like portals dimensions, migration , Gate keepers that open heaven over your etc.

You are merely sounding weird and sophisticated but loosing your audience and so not edifying them

Make it simple man of God.
