I've always been intrigued how Jesus referred to himself as 'the Vine'...when I think of a vine as opposed to a tree a vine moves, creeps, manoeuvres, goes around. Not much can get in its path and when something does, well, the vine just goes around, over or under, relentlessly moving and reaching out. Perhaps this is what Jesus meant when he said the gates of hell shall not prevail against him and the church.
