We have begun to answer the question, “Who am I?”, with the fact that we are all creatures, created in the image of God, dependent on him, and accountable to him. This is true of everyone born into the world whether we realize it or not. But for those of us who have trusted in Christ as our Savior, there is much more to our identity than simply being creatures.
The answer to the question “Who am I as a Christian?” is far more elaborate and wonderful than the answer to the simpler (if still profound) question, “Who am I as a human being?” Once we are converted, there are seven additional glorious truths that come into play as essential components of our identity. These will constitute our focus for the remainder of this book.
As we seek to answer that more elaborate question, it is beyond dispute that we must start with the fact that we are “in” Christ Jesus.
What does it mean to be in Christ? Is it a question of location, like being in a house? Is it something like belonging to a club or an organization? No, the term “in Christ” is the apostle Paul’s shorthand expression for being united to Christ. It is one of Paul’s favorite expressions, and (including similar expressions such as “in him” or “in the Lord”) Paul uses it more than 160 times in his letters. Clearly this is an important concept in Paul’s theology. And it should be an important concept for us because all the remaining answers to the question, “Who am I?”, are based upon the fact that we are in Christ, or we are united to Christ. This of course begs the question, what does it mean to be united to Christ? To answer it, we begin with 1 Corinthians 15: 22, “For as in Adam all die, so also in Christ shall all be made alive.” Note the two expressions “in Adam” and “in Christ.”
