The narrow bridge passage way to heaven can still be found while there is still time on this earth (John 3:16-18).. However, the day is soon coming when this bridge will be burned down forever (Malachi 4:1) (2 Peter 3:10) (Revelation 8:1-13).
Jesus, the only begotten Son of God is the only one with power to gain access across this narrow passage way; and he says:
“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).
“I am the way, the truth, and the life: no man cometh unto the Father, but by me” (John 14:6).
“Then cometh the end, when he shall have delivered up the kingdom to God, even the Father; when he shall have put down all rule and all authority and power” (1 Corinthians 15:24).
“And the seventh angel poured out his vial into the air; and there came a great voice out of the temple of heaven, from the throne, saying, ‘It is done’” (Revelation 16:17).
