Yes, union with Christ is indeed liberty. It is freedom. But real freedom in Christ is the freedom to NOT exercise my freedom. Real freedom is the ability to put love above liberty. To bind my liberty with love’s demand – the demand of the life of Christ that calls for self-sacrifice and submission to the conscience of my brothers and sisters. This is the law of love. This is Christ in me. This is “to live is Christ.”
“To live is Christ” has made the impossible unconditional love of neighbor possible. When we remember each day that Jesus loves us, his neighbor, as much as he loves himself, it is then that we can find the freedom to move past our unworthiness and the default of earning love, and move into the freedom of a love given to us simply because we are God’s neighbor.
