(CNN) - The Bible is a gritty book. Very raw. Very real. It deals with people just like us, just as needy and screwed up as we are, encountering a God who would rather die than spend eternity without them.

Yet despite that, it seems like Christians are uncomfortable with how earthy the Bible really is. They feel the need to tidy up God.

For example, look in any modern translation of Isaiah 64:6, and you’ll find that, to a holy God, even our most righteous acts are like “filthy rags.” The original language doesn’t say “filthy rags”; it says “menstrual rags.” But that sounds a little too crass, so let’s just call them filthy instead.

And let’s not talk so much about Jesus being naked on the cross, and let’s pretend Paul said that he considered his good deeds “a pile of garbage” in Philippians 3:8 rather than a pile of crap, as the Greek would more accurately be translated.

And let’s definitely not mention the six times in the Old Testament that the Jewish writers referred to Gentile men as those who “pisseth against the wall.” (At least the King James Version got that one right.)

The point?

God’s message was not meant to be run through some arbitrary, holier-than-thou politeness filter. He intended the Bible to speak to people where they’re at, caught up in the stark reality of life on a fractured planet.

Dozens of Psalms are complaints and heart-wrenching cries of despair to God, not holy-sounding, reverently worded soliloquies. Take Psalm 77:1-3: “I cry out to God; yes, I shout. Oh, that God would listen to me! When I was in deep trouble, I searched for the Lord. All night long I prayed, with hands lifted toward heaven, but my soul was not comforted. I think of God, and I moan, overwhelmed with longing for his help” (New Living Translation).

And rather than shy away from difficult and painful topics, the Old Testament includes vivid descriptions of murder, cannibalism, witchcraft, dismemberment, torture, rape, idolatry, erotic sex and animal sacrifice. According to St. Paul, those stories were written as examples and warnings for us (1 Corinthians 10:11). So obviously they were meant to be retold without editing out all the things we don’t consider nice or agreeable.

I believe that Scripture includes such graphic material to show how far we, as a race, have fallen and how far God was willing to come to rescue us from ourselves.

God is much more interested in honesty than pietism.

And that’s what he gives us throughout Scripture, telling the stories of people who struggled with the same issues, questions and temptations we face today.

Peter struggled with doubt, and we hear all about it.

Elijah dealt with depression; Naomi raged with bitterness against God; Hannah struggled for years under the burden of her unanswered prayers.

David had an affair and then arranged to have his lover’s husband killed. Noah was a drunk, Abraham a liar, Moses a murderer. Job came to a place where he found it necessary to make a covenant with his eyes not to lust after young girls (Job 31:1).

It’s easy to make “Bible heroes” (as Protestants might say) or “saints” (as Catholics might refer to them) out to be bigger than life, immune from the temptations that everyone faces.

I find it encouraging that Jesus never came across as pietistic. In fact, he was never accused of being too religious; instead he partied so much that he was accused of being a drunkard and a glutton (Matthew 11:19).

Jesus never said, “The Kingdom of God is like a church service that goes on and on forever and never ends.” He said the kingdom was like a homecoming celebration, a wedding, a party, a feast to which all are invited.

This idea was too radical for the religious leaders of his day. They were more concerned about etiquette, manners, traditions and religious rituals than about partying with Jesus. And that’s why they missed out.

That’s why we miss out.

According to Jesus, the truly spiritual life is one marked by freedom rather than compulsion (John 8:36), love rather than ritual (Mark 12:30-33) and peace rather than guilt (John 14:27). Jesus saves us from the dry, dusty duties of religion and frees us to cut loose and celebrate.

I don’t believe we’ll ever recognize our need for the light until we’ve seen the depth of the darkness. So God wasn’t afraid to get down and dirty with us about life and temptation and forgiveness. And grace.

Only when the Bible seems relevant to us (which it is), only when the characters seem real to us (which they were), only then will the message of redemption become personal for us (which it was always meant to be).

We don’t need to edit God. We need to let him be the author of our new lives.
