In him was life, and the life was the light of men.(John 1:4, ESV)
This same ever-existent living Word, who is truly God, who has created everything, is also full of life and light. When we say someone is "full of life" what we normally mean is that they are exuberant or energetic. Sometimes that full-of-lifeness is even a bit contagious. But this is only a glimmer of the full-of-lifeness that Jesus has. In Him is really Life! It is more than a feeling of exuberance or an attitude change. It illuminates. It Liberates. Truly free to live a life in God. The Life in Jesus will actually give you Spiritual Life and eventually an incorruptible body for your Eternal Life.
