I noticed that if I sat directly below one of the lights, both of my legs cast a separate shadow. Two legs, two shadows. Much like when we are in a relationship with someone, each person casts a separate shadow. Even though the light of God may be present in one or both of their lives, they are still living apart from one another. They aren't allowing God to transform their lives.
Then God said to me, this is not all I want you to learn from this. He said for me to get out of the way. I was kind of floored to be honest. Instead of getting upset or ignoring that thought in my mind, I instead began to wonder how I was in the way. Then it hit me. Shadows are only cast when something is blocking the light. All of us have to get out of the way of God's light, and stop putting ourselves in the way of Him. If we all step back and let God guide us, allow His light to not only surround us, but to fill us to the top, then there won't be any shadow at all. Only light. We will shine with the light of God.
