Do a half-way decent job of raising them from the beginning and you should be fine. This is the bar of raising children we're at.
1) Read to them EVEN AS A BABY from the Bible and throughout childhood.
2) Build trust by not abusing discipline, and allow them (all your children actually) to tell you anything and any opinion, even about yourself (accept that you may be wrong, even if told by your child) as long as they are respectful.
3) From the outset enforce a good and realistic self-image that will repel outside influences. Self-image psychology can literally imbue a human being with new talents and abilities in a matter of days, because humans are a goal-driven species and the brain-nervous system can't tell the difference between a real experience and a synthetic experience (I mean new abilities like being an all "F" student to being a "straight A" student, not because of positive thinking, but because your goal-achieving ability in your own eyes knows you are able to do it).
4) Show Christianity but in a rational way. Don't act like "this is my faith and I practice it so I'm right", or "God says this is sin so don't do it." Explain every single detail of this religion. First you must make yourself knowledgeable and learn to answer all questions. If they ever ask how do we know God exist, know all the arguments for this. If Jesus and the resurrection was real, know all the arguments for that, and so on. They will likely have an edge period, let it ride out. Also do not sin much ever in their presence.
5) Minimize media and technology, it destroys no matter what the content is. Also accept that your child has around a 50% chance to get addicted to porn no matter what you do, read this book attached in advance and know the techniques he teaches to help people permanently get over that.
