Tip #1. Dip into Christianity's intellectual traditionhttp://www.abc.net.au/news/2014-04-18/dickson-tips-for-atheists/5397892
This is the 1,984th Easter since 7 April AD 30, the widely accepted date among historians for the crucifixion of Jesus (the 1,981st if you find the arguments for 3 April AD 33 persuasive). Christians have been pondering this stuff for a long time. They've faced textual, historical, and philosophical scrutiny in almost every era, and they have left a sophisticated literary trail of reasons for the Faith.
My first tip, then, is to gain some awareness of the church's vast intellectual tradition. It is not enough to quip that 'intellectual' and 'church' are oxymoronic. Origen, Augustine, Philoponus, Aquinas, and the rest are giants of Western thought. Without some familiarity with these figures, or their modern equivalents - Pannenberg, Ward, MacIntrye, McGrath, Plantinga, Hart, Volf - popular atheists can sound like the kid in English class, "Miss, Shakespeare is stupid!"
“You'll get mixed up, of course, as you already know. You'll get mixed up with many strange birds as you go. So be sure when you step. Step with care and great tact and remember that Life's a Great Balancing Act. Just never forget to be dexterous and deft. And never mix up your right foot with your left.” - Dr. Seuss
