If you believe Jesus Christ and become God's child, you can gain the citizenship of Heaven. However, this is not the end. We have to live by the Words of Jesus who is the Way, Truth, and the Life until we finish our earthly lives. They are concerning His commands to do something, not to do something else, to throw something away, and to keep something, as are found in the Bible. It is just the way we can get to our destination without problems when we follow signposts on the highway. If we obey the Word of God in the Bible we can get to New Jerusalem, the best dwelling place in Heaven, without going astray (John 14:6).
