Never think for one solid moment that Jesus is not with you. Before you, beside you, beneath you. He is there with and for you.
It is your decision to keep this in mind. On my bike one day, I thought about God for a moment and as I realized that I was thinking about Him, I decided that it was important to remember to think about God tomorrow and every day. Not sure how old I was, but I was still loving my bike and riding it all the time, maybe 8 or 10 years old?
God has been in my head ever since and I plan on remembering Him tomorrow too.
