In John 17:3 Jesus defines eternal life, not in terms of time, but relationship. Eternal life is to know the only true God and Jesus Christ, who He sent. But who is the One True God? What is the true God like? How does one know this God? This sermon answers these questions and how the true God is Father, and that He is Almighty. The fact that this is our God has far reaching implications for both Christ's church and for individual Christians is also explored.
