Gillian, our 2 1/2 year old today asked the question, "where is Jesus?"
Now, there is an interesting concept to explain to a toddler. Kristi tried to explain it earlier and gave me a chance at dinner. So, after much thought, I calmly gave a dissertation (with small words) on the complexities of the Incarnation, followed by a soliloquy regarding the resurrection (Mel, you might want to look into that one) and the ascension with a quick word on the Holy Spirit and how we can communicate with Jesus in that manner.
Actually, I just said "he is right here with us." She acted like she understood. Yeah, right. I could explain that he is like your imaginary friend, except he actually exists.
I am sure the questions get deeper from now on. Hopefully we will spend a few years in the concrete before staying in the abstract concepts of theology.
