Father Daniel Berrigan once said, “Before you get serious about Jesus, think carefully about how good you are going to look on wood!”

That’s a needed caution because Jesus warned us that if we follow him, pain will flow into our lives and we will join him on the cross.

What exactly does that mean? Is pain laid on a disciple as some kind of test? Does Jesus need his followers to feel the pains he experienced? Does God want the followers of Jesus to undergo pain to help pay the price of sin? Why does accepting to carry the cross with Jesus bring pain into our lives?

It’s interesting to note that the great mystic St. John of the Cross uses this, the inflow of pain into our lives, as a major criterion for discerning whether or not we are authentically following Jesus. For John, you know you are following Jesus when pain begins to flow into your life. Why? Does God lay special pain on those who take Christ seriously?

No. God doesn’t apportion special pain on those who take Christ seriously. The pain that flows into our lives if we take Christ seriously doesn’t come from God. It flows into us because of a deeper openness, a deeper sensitivity, and a new depth on our part. The algebra works this way: By authentically opening ourselves up to Christ we cease being overly self-protective, become more vulnerable and more sensitive, so that life, all of it, can flow into us more freely and more deeply.

And part of what now flows into us is pain: the pain of others, the pain of mother earth, the pain of our own inadequacy and lack of altruism, and the pain caused by the effect of sin everywhere. This pain will now enter us more deeply and we will feel it in a way we never did before because previously we protected ourselves against it through insensitivity and self-focus.

Happily, this has a flip side: Just as pain will now flow into our lives more freely and more deeply, so too will meaning and happiness. Once we stop protecting ourselves through self-absorption, both pain and happiness can now flow more freely and more deeply into our hearts, and we can begin to breathe out of a deeper part of ourselves.

Freud once commented that sometimes things can be best understood by examining their opposites. That’s partially the case here. The opposite of someone who opens herself to pain, who opens herself to the pain of the cross, is a person who is callous and insensitive (in slang, someone “who is thick as a plank!”). Such a person won’t feel a lot of pain — but won’t feel much of anything else either.

A number of implications flow from this.

First, God doesn’t lay pain on us when we become followers of Jesus and immerse ourselves more deeply in the mystery of Christ and the cross. The pain that ensues is intrinsic to the cross and is felt simply because we have now ceased protecting ourselves and are letting life, all of it, flow into us more freely and more deeply. Happily, the pain is more than offset by the new meaning and happiness that are now also felt.

Second, experiencing the pain that flows intrinsically from discipleship and the cross is, as John wisely puts it, one of the major criteria that separates the real Gospel from the Prosperity Gospel. When the pain of the cross flows into our lives, we know that we are not feather-bedding our own self-interest in the name of the Gospel.

Third, it’s worth it to be sensitive! Freud once said that neurosis (unhealthy anxiety) is the disease of the normal person. What he didn’t say, but might have, is that the antithesis of anxiety (healthy and unhealthy) is brute insensitivity, to be thick as a plank and thus protected from pain — but also protected from deeper meaning, love, intimacy, and community.

If you are a sensitive person (perhaps even an over-sensitive one, prone to depression and anxiety of all sorts), take consolation in that your very struggle indicates that you are not a calloused insensitive person, not a moral boor.

Finally, one of the implications of this is that heaven isn’t the same for everyone. Just as pain can be shallow or deep, so too can meaning and happiness. To the degree that we open our hearts to depth, to that same degree deep meaning and happiness can flow into us. A closed heart makes for shallow meaning. A heart partially open makes for some deep meaning, but not full meaning. Whereas the heart that is fully open makes for the deepest meaning.

There are different depths to meaning and happiness here on earth and, I suspect, that will be true too in the next life. So, the invitation from Jesus is to accept the pain that comes from the wood of the cross rather than being thick as a plank!
