We’ve all heard the admonition to reflect on “what would Jesus do” and then conduct ourselves in the same manner. This advice brings up the question, though, of how do we know what Jesus would really do in our particular situation? In some cases he showed compassion and reservation, such as when he spared the woman caught in adultery. At other times he showed judgment and passion, such as when he turned the tables of the money-changers in the temple. How can we really know which way he would deal with each situation, or even the things he would do that don’t even occur naturally to our minds?

Anticipating the behavior of another person typically requires a deep and intimate knowledge of that person. This is something else we are encouraged to develop: a personal and intimate relationship with Jesus. We are told that we ought to know his personality, his manner, his attitude. But once again, how do we do that when he isn’t here in the flesh?

Of course, we can glean some of Christ’s personality and pattern of behavior from the Biblical account, and we might gain further insights through personal, spiritual experiences, but there is also a third way that is perhaps the most reliable method of them all. Jesus told his disciples: “I am the light of the world: he that followeth me shall not walk in darkness, but shall have the light of life” (John 8:12). Paul later confirmed to the Corinthians that he had sensed this light of Christ shining within him: “For God, who commanded the light to shine out of darkness, hath shined in our hearts, to give the light of the knowledge of the glory of God in the face of Jesus Christ” (2 Corinthians 4:6). This light of Christ is in all of us, even in those who have not yet accepted Christ. It is the conscience that always persuades us to do what is right. And this conscience is the key to learning who he is.

When we feel our conscience whisper in our hearts and we follow its counsel, we are at the same time both learning the nature of Jesus Christ and also doing what he would do. The conscience is telling us how he would behave in this instance, and as we do the same we feel his emotions and desires come alive in our own hearts. Thus, the prick of the conscience is an invitation to actually be Christ for a moment, and we are educated to his nature from within our very own selves!

Of course, this is also why following our conscience typically feels so strange and unnatural to us. It almost always means setting aside our own personality and choices, and stepping into an entirely different personality and pattern of behavior. This is a hard thing to do, but the more we practice it the more natural it becomes. Bit-by-bit we will be transformed from our old nature into Christ’s, taking on his attitude and likeness until we become his true representative. Thus, we can come to a deeper and more intimate knowledge of Christ than any other person. We will know him even as ourselves, because we will ourselves be as him.

If you truly want to know who Christ is, the tool to do so is already there in your heart. Practice bending yourself to the light he has put in you, and you will become a foremost expert on who the man really is. And then, everyone who sees you will also see the image of their Savior, and learn of him by you.
