Walking with Christ begins by realizing that we live life in two different realms. We are too often focused on living life by strict rules in the realm of earth, ignoring the fact that our connection to Christ introduces us to the realm of His kingdom. This is where our energies should be focused. Living in this realm means less of a focus on restrictive rules to protect us from the realm of earth and more striving to engage with God's kingdom. As we do this, we will find that our engagement with the world deepens in meaningful ways, which are detailed as Colossians continues.
As we continue the series in Colossians, we see the practical application of what it means to worship the cosmic and yet personal Christ that was introduced in the first section. This section takes the mystery of who Christ is and applies it to the lives of a community of faith. Instead of pursuing some other kind of mystery, they are called to dive into the mystery of Christ and watch how it transforms every aspect of their lives. There are particular applications to community life, legalism, character, family, professional life, religious expression, and more. This is the beauty of life with Christ: we worship a cosmic Christ who is far outside the realm of our normal lives and yet that very worship completely transforms the day to day life that we live in this world.
