The story of Tug and Arnie was inspired by the truth that is found in the gospel of John Chapter 15 where Jesus compares himself to the vine and calls us his branches and God the father is the vine dresser the gardener. There to prune and tend the vines and its branches to assure growth and fruition.
We are encouraged to abide in the vine, in Jesus, and then he will abide in us. Encouraging in us the ability to bear fruit, while providing the nutrition needed to endure the pruning in other words the trials we face. It is also the only place we can find true rest confident that no matter what if we remain attached to Jesus, he will display his glory through us.
