An often overlooked impetus of the Reformation was Luther's bashing of celibacy and emphatic promotion of marriage in its stead; marriage, take note, in a day without the Pill. This had the effect of emptying the monasteries and convents of the day. Luther started a sexual revolution; in marriage the repressed passions of the men and women found legitimate expression. This sexual aspect added tremendous force to what we commonly look at today as a purely doctrinal event. It's highly probable Luther's 95 Theses would have had little effect apart from the 69.
Consider, the Song of Songs is notorious for its explicit portrayal of erotic sex between a man and a woman, and it is not even clear if the two lovers are married. The emphasis is not on the marriage covenant, but instead the erotic love. Perhaps the Song's emphasis is the sole reason our Creator providentially placed it in our bibles, to counteract our tendency toward the opposite: celibacy and prudery.
In the opening of Paul's letter to the Romans, he specifically notes the fallout from godlessness as it relates to sexual relations:
“...for their women exchanged the natural function for that which is unnatural, and in the same way also the men abandoned the natural function of the woman and burned in their desire toward one another, men with men committing indecent acts and receiving in their own persons the due penalty of their error.” Romans 1:26-27 NASB
Notice in these verses the emphasis is not on lesbianism or homosexuality as is commonly taught, but on the shunning of childbirth by both women and men. The gist of the passage has as much to do with Christian women and men who avoid marriage and children, as the lesbian women or gay men who regularly catch the brunt of this exposited verse.
Hot sex and children are to go hand and hand.
That said, it is doubtful we will ever see a powerful resurgence of the Gospel without a corresponding resurgence of erotic Christian marriage; marriage that in addition to producing mutual orgasmic romance, also produces children to replicate the love.
This, is what Christ will honor.
