What is a cult?

The only sure way to avoid being deceived by a cult.

Short Answer

A Christian’s attitude toward Secular/Religious Humanists, Atheists, Agnostics, or members of any other New Age religion should be an attitude of love, concern, and compassion. We know that evolution isn't science. God offers His gifts to us, but does not force any of His gifts on anyone. Many will choose spiritual death and we need to pray for them, not disrespect them. They will disrespect us and be angry with us. They have a history of violence. They have a history of using many clever tricks to deceive and they have no Bible to tell them not to lie or even to define what a lie is.  Be aware that almost all of the media is either totally controlled or heavily influenced by Secular Humanism, as is the educational system on all levels.  Do not be deceived.  Do not sit in the counsel of the ungodly.  Be wise as serpents and harmless as doves.

Detailed Answer

How should a Christian treat an evolutionist? With Christian love and respect, but be aware that the worldly would love to try to squeeze you into their mold. Romans 12:2 Proverbs 13:20 Don't demand respect in return, because you probably won't get it. You will have to learn to turn the other cheek.

You will have keep in mind that you are dealing with someone who does not share your values. An unbeliever has a totally different idea of what truth is and has no solid reason to tell the truth. They do not even have the Bible to tell them the difference between a lie and the truth. They will probably believe in relativism, which means that they don't even believe that absolute truth exists. They do not have the Spirit of God. Be careful.

A Christian would benefit a great deal from educating himself or herself about the things that have been observed that show the hand of God in creation. Christians should know that there is no proof of evolution other than speculatively rationalized proof. Speculatively rationalized proof is not valid because rational-lie-zed speculation is simply making things up, fanaticizing, and claiming that those made-up fantasies are facts.

Christians should realize why evolution has been proven to be a scientific impossibility. It is good to know the real facts and to know the tricks used by evolutionists.

A proponent of New Age or of Humanism has nothing to fear in being open to a mutually respectful discussion of evolution and creation. However, if you didn’t realize that evolution is one of the highly protected dogmas of a religious cult, the religious zeal of evolution’s witnesses would seem weird. You would wonder why evolutionists become mean-spirited just because their ideas are challenged. If you didn’t know that evolution is vital to the existence of the New Age and to the Humanist religion, then you would expect evolutionists to have an open mind. Especially when there isn't a single bit of conclusive evidence that even can show that evolution is a remote possibility, you would expect that people who claim to be part of the scientific community would be questioning the teaching of evolution.

Of course evolutionism is part of a cult that needs evolutionism to survive. That’s what the big deal is. When you get the facts on this so-called theory, it's pretty hard to take it seriously. And evolution has never brought about a single advancement that has helped mankind, so why are they so religious and hateful about it? Because Humanism is a religion without the Holy Spirit that flows from Jesus Christ. When religion goes away from Jesus Christ, it either goes into spiritual deadness or it goes into religious violence and hate.

Proponents of Humanism get upset when Christians tell of what God is doing in their lives, and this is true even though the New Age religion still owns all the media, the schools, the entertainment industry, the news agencies, virtually every mode of communications. You would think they would be more tolerant, but they say that serving Christ is intolerable. You would think that these proponents of Humanism would learn to show the same restraint that the vast majority of Christians show as they watch the same proponents of Humanism use tax dollars to teach the major tenets of the Humanism religion in the schools. It's not as if the followers of Humanism had creation forced on them from every angle in the same way the Christians have the rational-lie-zed speculations Humanism forced on them.

And it's not as though there were a threat of violence from true followers of Christ. Christ forbids it. Christians must be careful not to follow the worldly example. There is not a single instance, in Scripture, of righteous anger on the part of a human. God is the only one who can be angry and righteous.

Some religions have been propagated by threat of violence. Over a thousand years ago, the speculatively rationalized so-called Christianity of some who lived during the dark ages (under a church government that had mostly turned away from God’s Word and the leading of the Holy Spirit) was such a religion that often used violence. Keep in mind that there were always those who followed Jesus, but, worldliness did creep in and affect the faith of many. Anger has always come from the spiritually dead against those who want to go on to a deeper experience with Jesus Christ. I hope that the Catholic denomination has advanced since then and is more back to the Bible and moving away from the false knowledge of speculative rationalism. (I’ve met many Catholics, some of them priests, who are indeed having a living experience with the Living Christ. I’ve met others who, unfortunately, mix in Humanist religiosity with their faith as one would mix sewer water with drinking water.)

Hindu, Islam, and Buddism have sects that use violence to propagate their religion.

The Humanist religion has killed many to propagate itself and continues to do so.

There are many who use religion as a cloak for political exploits, some of whom claim to act as Christians, but Christ is not leading them in their violent acts.

There are many other cults that have been guilty of propagating their religion through violence.

Never once, however, has the Spirit of God led a follower of Jesus to use violence to try to force anyone to believe in Jesus, as 1 Corinthians 14:38 states. God puts out the option. He offers salvation, but He doesn’t force Himself on anyone. Those who choose hell have made their own choice. And God lets them go that way when they choose to.

In theory, most evolutionists would surely claim to have an open mind. Why would anyone get so dogmatic about a theory when they personally have never seen any actual evidence for the theory. No one has seen actual evidence for evolution. No one. In practice, though, proponents of Humanism are only open-minded to their own preconceived ideas. Only God can open their minds.

A follower of Humanism has nothing to fear in being open to a mutually respectful discussion of evolution and creation. Arguments or debates don't accomplish anything, but a good, positive discussion of the facts is worthwhile. Those who don't want to know the Truth cannot be argued into accepting the Truth, because it takes the work of the Holy Spirit to turn a person's heart to the Truth; The Truth is a person, Jesus Christ. When an evolutionist realizes that evolution is a scientific impossibility, perhaps it would be a good thing for them to look for a new idea. God is real. Jesus is really the way that God gave for us to return to Him. Take hold of it. This Jesus is for you.

Summary

Zealots of Secular/Religious Humanism, Atheism, Agnosticism, and any other New Age religion need our concern, compassion, and prayers. They need to hear the truth, too, but not coercion, anger, or disrespect. They will coerce, become angry, and disrespect as they have a history of violence and of using many clever tricks to deceive. Evolution isn't science.
