Nicodemus asked Jesus what must he do to inherit eternal life. He said to him you must be born again, how he asked, of the spirit. Your saved from spiritual death, when you accept him he recreates us new, as in born of the Father's spirit. Looked on web, says their equivalent same thing. To me a person could be saved, today, or a week, a year, or ten, but if your born, then you need to grow, this is the problem some believe, saved, and sow your wild oates, no spiritual growth. Staying a baby, in the milk, where as we should grow into maturity and partake of strong food, as meat, bible verse.
