We are all atheists when it comes to belief in the gods of the past, like zeus, mithras, thor. What is it about the abrahamic version of god that suggests that belief will persist? 

No one can lay any foundation other than the one already laid, which is Jesus Christ. If anyone builds on this foundation using gold, silver, costly stones, wood, hay or straw, their work will be shown for what it is, because the Day will bring it to light. It will be revealed with fire, and the fire will test the quality of each person’s work. If what has been built survives, the builder will receive a reward. If it is burned up, the builder will suffer loss but yet will be saved—even though only as one escaping through the flames. (1 Corinthians 3:11-15)

Which belief? Persist in what way? 

Christians and Muslims each perceive they (we) have perfected Judaism. Both Muslims and Jews argue that Trinitarian Christians are polytheists in denial. Most Muslims and many Jews are scandalized by the notion that "God" would submit to a tortuous death at human hands, and are offended by the claim this scandal has redeemed humankind. Some Jews and Christians view Islam as a hotpot of theological flotsom and jetsam barely held together by the beauty of Mohammed's poetry.

Each of the Abrahamic versions of God have changed and continue to change. Today Christianity and Islam are being radically transformed.  My grandchildren's (if any) belief (if any) will almost certainly be considerably different than my own.  The mainstream of each religious tradition is in flood. Where the channel may settle is too soon to tell.

God unfolds in human experience.  The fullness of God is far beyond our individual or collective capacity.  But to fully encounter this unfolding, even briefly, is to be released from our innate antinomies and to step into the noumenal: this life-in-itself.
