Four year old children can be very naughty. They can make their mommies very mad. Yet, a loving Mommy would NEVER lock her four year old out of her house. So, why worry that God might lock us out of Heaven? The real worry is that we might reject Jesus, refusing His invitation to share His life.
While a loving Mommy would never lock her four year old out of her house, the four year old might walk away. I can well imagine a four year old saying, “I’m going to Grandma’s house. She’ll let me have a cookie.” A four year old might leave the comfort, safety, and happiness of his mother’s home for the mistaken idea that Grandma’s house and a cookie await.
This is the danger we all face. When we die, Jesus invites each and every one of us to join Him in Heaven. We choose whether to accept His invitation or to reject Him and go looking for the equivalent of that four year old’s cookie.
Which we will choose depends largely on the choices we have made as we lived our life on Earth. If we have developed strong attachments and desires for Earthly things, then we may well choose them, thus rejecting life with Jesus.
