Some things are just better off left un-touched. The Gospel of Christ tops the list as the most important. To change just a few things will completely destroy the power of its message, and the intention behind it.
As we look at Colossians 2:11-23, we see two truths: What Jesus did for us; and what Jesus asks of us.
Under each of those two headings, we see 3 main points:
What Jesus did for us:
He gave us complete salvation;
he gave us complete forgiveness, and he gave us complete victory.
What Jesus asks of us: Do not let anyone judge you;
Do not let anyone disqualify you;
Do not let anyone enslave you (beware of ascetescism)
