I was seeking God about understanding the Trinity and having trouble making the connection of how three were one and complete as one. It is amazing to me how God can use anything to help us understand.
Not too long after a friend of mine was describing her road trip up North and she told me about a sign she saw on a shop in a small rural town. The words on the sign were, Gifts, Guns and Snack Bar.
People in the town were able to purchase what they needed from the one shop. This is similar to the Trinity. (This is not a deep theological explanation but it helped me.)
We keep searching so many different things for fulfilment, our sense of purpose, peace and comfort.
God is our father and offers the full benefits of a loving father. Jesus is our Prince of Peace through whom we are a new creation and Holy Spirit is our Comforter.
This helped me at that time at the spiritual level of maturity that I had.
God has expanded my understanding in this area via revelation and study and I recommend taking the time to read up and seek God to increase our understanding of the wonderful Holy Trinity.
