Revelation 21:21 describes the New Jerusalem, which has twelve gates made of pearls. They are not pearly gates to the entrance of heaven, as the media often portrays. These gates are part of the new earth of the future, not an entrance to heaven when people die, and only the redeemed will enter through these gates. Heaven will be a place of immense beauty as well as eternal joy and peace with God, free from sorrow, pain, and death. To gain admittance, one must be forgiven by Jesus Christ and covered by His sacrifice, which is possible by trusting in His death and resurrection for the forgiveness of sins.
Heaven will be beyond imagination, and certainly the pearly gates will be dazzling. But the mere appearance of heaven pales in comparison to what it will be like. In heaven, there will be no sorrow, no pain, and no death—only everlasting joy and peace in the presence of God. This perfect reality invites us to live with hope, knowing that our struggles today are temporary and that we are destined for an eternity of unimaginable beauty and fulfillment with our Creator. No detestations or false people will be allowed to enter. All of us have done bad things; on our own, we're all banned from this place of perfection and beauty. So, how does a person gain admittance? To be written into the Lamb's book of life, a person must be forgiven by Jesus Christ and covered by His sacrificial blood. "Blessed is the one whose transgression is forgiven, whose sin is covered. Blessed is the man against whom the LORD counts no iniquity, and in whose spirit there is no deceit" (Psalm 32:1–2). By trusting in the sacrifice of Jesus, we become clean. By God's grace, through faith in Jesus Christ, we can be saved (Ephesians 2:8–9; Acts 4:12; Romans 10:9). John 1:12 tells us that those who are in Christ are children of God, and 1 Peter 1:4 says they will receive an eternal inheritance with eternity in God’s presence, in a place of immense light and beauty.
