Pastor and wife preach married sex with 24-hour 'bed-in'

This is for real, not a satire. 

And then one wonders why the church is not taken seriously?

To encourage members of his congregation and others to take part in what he calls a “sexperiment,” Dallas pastor Ed Young and his wife Lisa began staging a "bed-in" on Friday morning, laying in a bed on the roof of their Texas church for 24 hours.

They say they want to illustrate that sex begins in heaven.

“It’s time to put the bed back in church and God back in the bed because God is the one that thought sex up," says Ed Young, senior pastor of Fellowship Church.
