Christian love and secular humanism’s love are two different things.
Christian love is inseparable from the Law of God. Idolatry is not loving toward God. Dishonoring authority, murdering, committing sexual immorality, stealing, lying, and coveting are not loving toward our neighbors. Christian love has a strong negative, but it must go from the negative to positive. In the positive sense, Jesus lived an active life of love, obedience, and righteousness; in the negative sense, Jesus was sinless.
Secular humanism’s love is inseparable from the ideas of mutual respect and mutual benefit. This is why pornography can be OK if it is between consenting adults, but why rape is wrong. This is why homosexual practice is OK, but pedophilia is wrong. This is why cheating on a spouse is wrong, but if both spouses agree on an “open marriage” it’s OK. This is why from a secular perspective 50 Shades of Grey is so confusing: he’s abusing her, which violates mutual benefit, but she agreed to it and they’re consenting adults, so maybe it’s OK? If consent is the only criterion that determines whether a sexual act is moral or immoral, there are some serious difficulties. For example, a husband and wife can’t have passionate, spontaneous love-making because they have to stop every step of the way and both say a verbal “yes.” I strongly disapprove of this moral reasoning, but I hope I have represented it fairly.
God is disciplining the unfaithfulness of American Christians because we are trying to make compromises between Christianity and secular humanism. We are like Eve thinking we know better than God. Christians who start to approve of pornography, sexual immorality, abortion, “open marriages,” despising authority, etc. will find they have no moral leg to stand on. Approving of evil is evil. The reward for loving lies is more lies. Elijah said to the people of Israel, “How long will you go limping between two different opinions? If the Lord is God, follow him; but if Baal, then follow him” (1 King 18:21).
Jesus Himself says in the Sermon on the Mount, “Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them. For truly, I say to you, until heaven and earth pass away, not an iota, not a dot, will pass from the Law until all is accomplished. Therefore whoever relaxes one of the least of these commandments and teaches others to do the same will be called least in the kingdom of heaven, but whoever does them and teaches them will be called great in the kingdom of heaven. For I tell you, unless your righteousness exceeds that of the scribes and Pharisees, you will never enter the kingdom of heaven.”
By relaxing the Law of God, many American Christians are throwing away their reward.
