A Life Sentence
Most of us couldn't even imagine doing anything that would later have a judge say "I hereby sentence you to life." Unfortunately, too many people also can't imagine doing anything that will later have the ultimate Judge say, "I hereby sentence you to life - eternal life" (see also When Will You Be Judged?). Many Christian-professing people believe that by simply "accepting Jesus" they are guaranteed eternal life, but that same "Jesus" has a surprise coming for many who claim to be His people, while refusing to do what He actually said must be done:
"Every tree that bringeth not forth good fruit is hewn down, and cast into the fire. Wherefore by their fruits ye shall know them."
"Not every one that saith unto Me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of My Father which is in heaven. Many will say to Me in that day, Lord, Lord, have we not prophesied in Thy Name? And in Thy Name have cast out devils? And in Thy Name done many wonderful works?" [i.e. they will have used The Lord's Name in vain, as a personal vanity - see The Third Commandment to understand both meanings of taking The Lord's Name in vain]
"And then will I profess unto them, I never knew you: depart from Me, ye that work iniquity."
"Therefore whosoever heareth these sayings of Mine, and doeth them, I will liken him unto a wise man, which built his house upon a rock: And the rain descended, and the floods came, and the winds blew, and beat upon that house; and it fell not: for it was founded upon a rock. And every one that heareth these sayings of mine, and doeth them not, shall be likened unto a foolish man, which built his house upon the sand: And the rain descended, and the floods came, and the winds blew, and beat upon that house; and it fell: and great was the fall of it." (Matthew 7:19-27 KJV)
Eternal life is the freely-provided gift of grace to those who live God's way, not their own way in God's Name. The "many roads to the same place" philosophy is true of the lake of fire, not to the Kingdom of God.
"Enter ye in at the strait gate: for wide is the gate, and broad is the way, that leadeth to destruction, and many there be which go in thereat: Because strait is the gate, and narrow is the way, which leadeth unto life, and few there be that find it." (Matthew 7:13-14 KJV)
