I never said that I don't like apologetics. I'm just saying that it would off-topic (or at the very least, not the main topic) on this thread. Even if we grant, for the sake of argument, that there is compelling evidence to believe in a historical resurrection of Jesus, how do you move on from that to answering the questions asked in post #1?
If the resurrection of Jesus was supernatural, does that mean that a personal relationship with Jesus & God is also supernatural?
I'm not sure if I would say that the personal relationship to God is supernatural. Our "normal" relationships can also be very different. For example, when you have a pen pal or talk to a friend on the phone then it's not supernatural, and our relationship with God is quite similar to that. We cannot see God, but we can talk to him (like on the phone) and he responds (often) through the written word, the Bible, like a pen pal.
There are supernatural aspects to our relationship with God though, because God interacts in various ways with us that people cannot do.
The answers to the questions you asked in #1 may differ from person to person because our relationship with God is unique and individual. However, I think it is fair to say that Christianity is not based on feelings. Similarly to "normal" relationships it doesn't depend on some warm and fuzzy feeling but on the
knowledge and
experience that your friend is really your friend.
Allow me to answer your questions according to my
personal knowledge and experience.
- When does the relationship begin?
Sin is like a chasm between God and man. Because of his holiness God cannot have a real relationship with the natural human being. Jesus Christ bridged that chasm by the cross. His death and resurrection justifies those who believe in him, and only through Jesus we have access to the Father, allowing us to have a real relationship with God. When we put our faith in Jesus we become children of the living God, and that is when our relationship with him begins.
- How do you know that the relationship has begun? Is there some specific event that makes the beginning of the relationship obvious?
Simply put: it becomes obvious by your desire to talk to God. Non-Christians don't have that desire, but when you have the Holy Spirit you
will want to talk to your heavenly Father.
And without communication there is not much of a relationship, right?
- Is this relationship a two-way interaction? Does God speak to you in supernatural ways, for example?
Our relationship with God is certainly a two-way interaction, although there are times where God just listens. He speaks in various ways to us - in the Bible, through other people and even through circumstances. God opens doors and closes doors to lead us. His Spirit is very skilled in putting Bible verses into our mind that we need in a certain situation.
- Does this "relationship with God" involve having supernatural experiences with God on a frequent basis?
I guess the answer to this question depends on what you define as "supernatural". I have experienced real miracles in my life, but when I look back at my life I see God's guidance in many more occasions and situations.
"Supernatural experiences" as an atheist would define it are not frequent though. God wants us to be humble servants and not puffed up people.
- How do you know that this "relationship" is real and not just your brain playing tricks on you? How do you know that a real God is genuinely having a personal relationship with you?
How do you know that your friend has a relationship with you? By knowing that he is real and by the experience that the things he says prove sincere.
When we commit to God and simply trust him then we will experience that he does everything he promised. We will notice that our prayers get answered - not always the way we expect it, but they do get answered. And while our relationship with God doesn't
depend on any feeling there is actually something God gives us that nothing else in the world is able to give us: a kind of inner peace and serenity that exceeds every imagination.
