How should Christians respond to the issue of homosexuality & so-called homosexual marriage?

"My Eyes Shed Streams of Tears"— Thoughts on the New Calamity by John Piper

Jesus died so that heterosexual and homosexual sinners might be saved. Jesus created sexuality, and has a clear will for how it is to be experienced in holiness and joy.

His will is that a man might leave his father and mother and cleave to his wife, and that the two become one flesh (Mark 10:6-9). In this union, sexuality finds its God-appointed meaning, whether in personal-physical unification, symbolic representation, sensual jubilation, or fruitful procreation.
For those who have forsaken God’s path of sexual fulfillment, and walked into homosexual intercourse or heterosexual extramarital fornication or adultery, Jesus offers astonishing mercy.

Such were some of you. But you were washed, you were sanctified, you were justified in the name of the Lord Jesus Christ and by the Spirit of our God (1 Corinthians 6:11).

But last weekend this salvation from sinful sexual acts was not embraced. Instead there was massive celebration of sin.

One estimate said that 400,000 people celebrated gay pride in Minneapolis. That’s more than the population of the city. The number is probably inflated, but for the first time in history, it did include the governor of the state, Mark Dayton.

The Bible is not silent about such parades. Alongside its clearest explanation of the sin of homosexual intercourse (Romans 1:24-27) stands the indictment of the celebration of it. Though people know intuitively that homosexual acts (along with gossip, slander, insolence, haughtiness, boasting, faithlessness, heartlessness, ruthlessness) are sin, “they not only do them but give approval to those who practice them” (Romans 1:29-32). “I tell you even with tears, that many glory in their shame” (Philippians 3:18–19).

This is what our governor was doing on Sunday along with millions of others across the country—knowing these deeds are wrong, “yet approving those who practice them.”

Not only that, we are moving from celebration to institutionalization. On June 24 the New York legislature approved a Marriage Equality Act. This makes New York the sixth state where so-called homosexual marriages will be institutionalized: Connecticut, Iowa, Massachusetts, New Hampshire, Vermont, (and the District of Columbia).

My sense is that we do not realize what a calamity is happening around us. The new thing—new for America, and new for history—is not homosexuality. That brokenness has been here since we were all broken in the fall of man. (And there is a great distinction between the orientation and the act—just like there is a great difference between my orientation to pride and the act of boasting.)

What’s new is not even the celebration of homosexual sin. Homosexual behavior has been exploited, and reveled in, and celebrated in art, for millennia. What’s new is normalization and institutionalization. This is the new calamity.

My main reason for writing is not to mount a political counter-assault. I don’t think that is the calling of the church as such. My reason for writing is to help the church feel the sorrow of these days. And the magnitude of the assault on God and his image in man.

Christians, more clearly than others can see the tidal wave of pain that is on the way. Sin carries in it its own misery: “Men committing shameless acts with men and receiving in themselves the due penalty for their error” (Romans 1:27).

And on top of sin’s self-destructive power comes, eventually, the wrath of God: “sexual immorality, impurity, passion, evil desire, and covetousness, which is idolatry. On account of these the wrath of God is coming” (Colossians 3:5–6).

Christians know what is coming, not only because we see it in the Bible, but because we have tasted the sorrowful fruit of our own sins. We do not escape the truth that we reap what we sow. Our marriages, our children, our churches, our institutions—they are all troubled because of our sins.
The difference is: We weep over our sins. We don’t celebrate them. We turn to Jesus for forgiveness and help. We cry to Jesus, “who delivers us from the wrath to come” (1 Thessalonians 1:10).
And in our best moments, we weep for the world. In the days of Ezekiel God put a mark of hope “on the foreheads of the men who sigh and groan over all the abominations that are committed in Jerusalem” (Ezekiel 9:4).

This is what I am writing for. Not political action, but love for the name of God and compassion for the city of destruction.

“My eyes shed streams of tears, because people do not keep your law.” (Psalm 119:136)
