Those who say they are not religious do not realize that their core beliefs and world view are in fact their religion! Every person has a religion and they think, speak, and act according to it. Some popular American religions include Big Bang/Evolutionism, Materialism, Statism, and Moralistic Therapeutic Deism.
Some chatter confidently about what they call “the Christian religion,” but actually are clueless about what being a Christian – a disciple of the Biblical Lord Christ Who makes absolute truth claims about Himself – means. Or, they have this straw man in mind: a small minded ritualist who adheres to externalistic rules of behavior.
Therefore the straw man fabricators often have a compulsion to apologize if they utter certain four letter words in the presence of the person they call “religious.” Or they might venture to ask “why MUST you go to church EVERY week?” never dreaming that gathering with fellow believers to worship God and be together is not some boring drudgery, but the high point of the week to which a Christian looks forward with joy.
“Pure and undefiled religion before God and the Father is this: to visit orphans and widows in their trouble, and to keep oneself unspotted from the world.” (James 1:27)
“For this is the love of God, that we keep His commandments. And His commandments are not burdensome.” (1 John 5:3)
