I'm going to give you some really strange advice on starting off on apologetics. Start with a good book on discrete mathematics, ignore evidentialists and only read presuppositional apologists (Van Til and company) but only after you have a good foundation for mathematical reasoning. If you are looking for lifelong study, this would be the ideal course of study. The reason I say this is that if you attempt to go the evidentialist route, they are all based on circular reasoning that has presuppositions, but they just don't know where their presuppositions start.
There is no good and logical necessity apart from the axioms of a system that give a foundation. The WCF states:
5. We may be moved and induced by the testimony of the church to an high and reverent esteem of the Holy Scripture. And the heavenliness of the matter, the efficacy of the doctrine, the majesty of the style, the consent of all the parts, the scope of the whole (which is, to give all glory to God), the full discovery it makes of the only way of man's salvation, the many other incomparable excellencies, and the entire perfection thereof, are arguments whereby it doth abundantly evidence itself to be the Word of God: yet notwithstanding, our full persuasion and assurance of the infallible truth and divine authority thereof, is from the inward work of the Holy Spirit bearing witness by and with the Word in our hearts.
Our confession states that our persuasion of the scripture is from the inward working of the holy spirit ... even if we have all those reasons to find it worthy of our trust, it is an axiomatic position; we accept it without any proof because of the Spirit working within us. In other words, even our acceptance of the Bible is presuppositional (to the extent that the assurance of the truth of it is not, and cannot be, because of outward evidence).
What Kant did was take the logical underpinnings of classical apologetics out from under the house. He did so through logic and reason, and did so well. What he (and no one else can) do is take out the underpinnings of presuppositional apologetics. The presuppositional start is Romans 1:18-21 with a non-believer. I do not attempt to convince someone of the truth of what they already know. What I do is show them the inconsistency of their own system (they borrow from the starting point of the existence of God) and tear down their house of cards. (While it is possible to be
logically consistent with not believing in God, it requires being a psychopath/sociopath in order to maintain that consistency, and while there are those that have suppressed the truth in unrighteousness that far, declaring the truth is what we are required to do, not convert souls.)
As to your reasoning, you cannot, by any means of wisdom or skill in parenting (or lack thereof), change whose names were written in the book of life before the foundation of the world. If God blesses you with children, their faith is founded on God's election, not your effectiveness in parenting. Just as God's election is a great comfort and incentive to evangelize those whom we meet, it is also a great comfort and incentive to parent the best we know how trusting God to provide the result. Our trust is that he has promised to be our God, and the God of our children. More we cannot do other than raise them in the nurture and admonition of the Lord.
Your desire to defend the faith needs to be tempered with a knowledge that no matter how effective you are at logical explanation, you cannot possibly control the outcome. Suppressing the truth that God has made plain to mankind is a moral issue, not a knowledge or reasoning issue. God has shown
everyone what is needed to know that he is, and is a rewarder of those who diligently seek him. It is only through unrighteousness that people suppress that truth. We are not better than God at convincing people of the Lord's existence ... yet evidentialists would seem to imply that if they could just argue a little better, know a little more, reason a little more clearly, people would see their need and repent. Repentance unto life is a saving grace that is given by God and is completely out of our control; we are to obey and trust the result to God who is in control.
Keep your enthusiasm to defend the faith ... it is possible that God will use you as an instrument in his hand to bring someone to faith whose name is written. But remember, it isn't based on your ability. Even at this point, you are capable of defending the faith to the extent that God demands of you at this point. Our study is more for our own edification than for our ability to win others to Christ (in ourselves, we have no ability to win others to Christ, and if the Holy Spirit is working, those whom we testify to will be won to the faith). Study to show yourself approved (to yourself!).
