I don't think they are exclusive. We are living in Christ's kingdom now. We are ambassadors for it in the world (but not of it). Our victory isn't in earthly governments or Christian politicians, it is in working for the kingdom in a way that can only ultimately come to fullness after the final judgement when heaven and earth are made new. Focusing on here and now (culture wars, zionism or nah, theological disputes, personality cults, etc.) to the exclusion of eternity is as useless as looking so much to eternity that we neglect the work that needs done here and now.
