The Lord Jesus Christ gives us an unmistakable imperative in Matthew Chapter 7. He says, "Enter ye in at the narrow gate: for wide is the gate, and broad is the way, that leads to destruction, and many there be which go in thereat: Because strait is the gate, and narrow is the way, which leads unto life, and few there be that find it." It is difficult to miss the two roads and the two destinies spoken of in these verses. Yes, there is a heaven; and yes, there is a hell. And the choice is ours as to which road we take and which destiny we arrive at. But only in the Bible will you find an honest and unbiased assessment of man's true nature and the unchangeable standards of God to which we must attain. But, yes, heaven IS attainable, not by our works or merit but by the work of Christ on the cross for us.
