Sample like Yogurt? You sound like you are against spiritual exploration. How can you commit so easily? Do you ever question or doubt your beliefs? I do all the time. Many people don't as it's the very foundation from which they stand.
I have been redeemed by Jesus Christ. I am convinced He is the Son of God, who died on the cross for mankind. Also, I believe the Bible is the Word of God. According to the Bible, there is no other way to Heaven than through Christ. Why would I waste my time with false belief systems?
However, I do often test my faith, but never "sample".2Co 13:5 Examine yourselves, whether ye be in the faith; prove your own selves. Know ye not your own selves, how that Jesus Christ is in you, except ye be reprobates?
