The religion of Jesus Christ is NOT irrational. In fact, when Paul went to preach the gospel to others, the scriptures say that he "reasoned" with them (Acts 17:2; 18:4; 18:19; 24:25). We are admonished to "prove all things" (1 Thess.5:19). John tells us to "try the spirits" (John 4:1). In dealing with matters of religion, we are to "speak as the oracles of God" (1 Peter 4:11).
How many times have you heard this one, "It doesn't matter what you believe." Don’t take that one to driving school. It will not pass. "The sign says 'STOP' but it just doesn't matter what you believe." Would you tell a police officer this? Imagine the conversation: "Officer, I know I was doing 80 in a 35, but, it doesn't matter what you believe."
How many times did Jesus say to reasoning adults, “Go ask your parents whether or not I am the Messiah?” He never did. What did He say? “You search the Scriptures, for in them you think you have eternal life; and these are they which testify of Me” (John 5:39). It wasn’t “go ask your parents,” but “the scriptures teach.”
Take a few salesmen and set them before potential clients and tell them to say, "You need to buy my product because I feel in my heart that it is right for you." The clients will leave. They want competence, not sentimentalism. They want good reasons to buy your product, not sappiness.
The decision of what religion to practice is of utmost importance! Man’s soul is more valuable than any automobile, house, or job. So, why would one put the decision of what to do with his soul in the hands of a child—and not only that, but merely based upon a child's likes and dislikes?!
