I was born in the 1950s, became aware of the larger world and moral issues in the 1960s (subjected as we all were during that era to the so-called sexual revolution), solidified my Christian faith in the early-to-mid 1970s, slipped away from Christian reality for a while after that, only to return to faith in the late 1980s with supreme gratitude to God for His patience and willingness to forgive my stupidity.

I was blessed to be brought back from the brink of spiritual destruction. As a result, I speak earnestly and forcefully (with love, I trust) about the need to hold fast to His truth and not allow slippage to occur, both in the individuals I have the opportunity to influence (students, in particular) and in my ongoing concern for the Christian church’s witness to the world.

When the church—which is comprised of all those who have come to the foot of the Cross, repented of sin, and received the forgiveness and grace only offered there—stops being the voice of God on moral issues, the culture degrades in proportion to the church’s apostasy.

This hasn’t happened on all issues. Take abortion, for instance. Despite the efforts of those who want to see abortion accepted as normal, great strides have been made by Christians in our nation to stem that tide. Regardless of the government’s promotion of abortion via the Supreme Court, the attitude of Americans on that issue is shifting more and more toward rejection of that horrific act.

Not so with homosexuality, unfortunately. This has become the primary issue now with the government and the culture in general (entertainment media, especially) in an attempt to overthrow Biblical morality.

Those of us who grew up in the 1950s-1970s era look around us and almost can’t believe what we see. What was once considered abnormal and not even to be mentioned publicly has become a celebration of “diversity.” Those who oppose the gay agenda are singled out as “haters,” “bigots,” and “narrow-minded.”

Same-sex marriage, from a Biblical standpoint, is an absurdity. Probably more than 90% of Americans would have said the same thing a mere twenty years ago. Now, even Republicans—you know, the “conservatives”—are on the verge of accepting it as normal. A recent poll revealed that nearly 50% of Republican voters no longer have a problem with it.

While that certainly concerns me as a conservative, the more pressing problem is the change occurring with those who claim to be Christians. The shift within the supposed Christian community is disheartening.

One Christian professor at a Baptist seminary has come up with a sad, yet from my perspective, accurate description of what is happening. He sees evangelicals moving toward the same acceptance of same-sex marriage as the overall culture.

Here are the stages he outlines.

(1) Oppose gay-marriage: Every evangelical starts here, or at the very least they appear to start here.

(2) Oppose taking a stand on the question: Persons in this stage are becoming aware of how offensive the traditional view is to those outside the church. Their initial remedy is to avoid that conflict by not talking about the Bible’s teaching on this subject. In Brian McLaren‘s case, he urged evangelicals to observe a 5-year moratorium on talking about gay marriage. For Jen Hatmaker, she advocated going “into the basement,” where we don’t talk about these things but just love people. Choosing to avoid the question is never a final answer for anyone in this stage.

(3) Affirm gay marriage: At some point during the “we’re not talking about this anymore” stage, those who used to oppose gay marriage find grounds to affirm it. Some do it by questioning the Bible’s truthfulness. Others do through revisionist interpretations of the Biblical text. In either case, proponents end up affirming what the Bible forbids.

(4) Vilify traditional marriage proponents: Persons in this stage not only affirm gay marriage. They also view traditional marriage supporters as supporting invidious discrimination against gay people. They will adopt the rhetoric of Christianity’s fiercest critics to describe believers who hold to the Bible’s teaching on marriage and sexuality.

The professor then goes on to state that while it may take some time for people to go from stage 2 to stage 3, once they hit stage 3, they quite often go rapidly into stage 4.

I teach at an evangelical university. During the Obama presidency, we, along with other evangelical universities, experienced pressure to change our public stand on this issue or else our students would be cut off from getting education loans and our accreditation might be withdrawn over time.

Some may think that just because we presently have a Republican Congress and a president who curries favor with evangelicals that we are “safe.” Believing that all is back to “normal” would be the height of wishful thinking.

It is crucial for those who truly know what it means to be brought out of the pit of sinful destruction and receive the mercy and grace of God to stand firm at this time on Biblical teaching about sin.

Many will twist my words, saying they are hateful. They are just the opposite. I want everyone caught in a sinful life to be set free. I needed that in my life at one point and God graciously gave me a new life. I seek the same for others.

All sin—homosexuality included—leads to chains that bind us. When we are in those chains, we get used to them and our consciences become seared. The Christian’s responsibility is, by the leading of the Holy Spirit, to break through that seared conscience with the twin weapons of Truth and Love so that those caught in the trap will see their need and respond to God’s mercy through Christ.

To be faithful to God’s truth and to speak to our society about that truth is the most loving thing we can do.
