“To live is Christ” is not the end of morality. It’s the beginning. The indwelling life of Christ has given us the knowledge of good and evil through the shared life of Christ.
Our minds can be renewed in love. The love of “to live is Christ.”
The law can reveal my holy God and my unholy self, but only the cross can crucify the flesh and only the resurrection can quicken the life of Christ in me (and it already has). This is the gospel. This is the new way of the Spirit. This is “to live is Christ.”
“To live is Christ” is to live by the Spirit of freedom. Freedom from the law and it’s condemnation. And freedom to trust the power of God’s love that has poured into every beating heart of every believer in Christ.
“To live is Christ” offers us true meaning. We share the divine nature of the last Adam. We have his life. His good life. Forever.
“To live is Christ” removes all of this childish, “human” behavior from our hearts. We no longer have to be the best, or promote our own self-worth. Our worth is in Christ. That is true spirituality – loving, giving, sharing, submitting. This is our super power.
