There are some prophecies about the last judgement in the Bible.
Isa 66:15 See, the Lord is coming with fire, and his chariots are like a whirlwind; he will bring down his anger with fury, and his rebuke with flames of fire.
2Ti 1:7 and give relief to you who are troubled, and to us as well. This will happen in blazing fire with his powerful angels.
Lk 18:8 I tell you, he will see that they get justice, and quickly. However, when the Son of Man comes, will he find faith on the earth?
Thus, what is more urgent is the prophecies about Jesus' second coming because if He come to this faithless world as the last judgement, who would be saved?
For this reason, Jesus Himself have to come again in the flesh to restore the truth of life and to seek His people.
Heb 9:28 so Christ was sacrificed once to take away the sins of many people; and he will appear a second time, not to bear sin, but to bring salvation to those who are waiting for him.
Then, how can we know the Second Coming Christ?
There must be a sign for us to recognize Him as our savior.
Jn 10:10 The thief comes only to steal and kill and destroy; I have come that they may have life, and have it to the full.
Jn 6:48 I am the bread of life.
Jn 6:53 Jesus said to them, "I tell you the truth, unless you eat the flesh of the Son of Man and drink his blood, you have no life in you. Whoever eats my flesh and drinks my blood has eternal life, and I will raise him up at the last day.
Mt 26:19,26 So the disciples did as Jesus had directed them and prepared the Passover... While they were eating, Jesus took bread, gave thanks and broke it, and gave it to his disciples, saying, "Take and eat; this is my body." Then he took the cup, gave thanks and offered it to them, saying "Drink from it, all of you. This is my blood of the covenant, which is poured out for many for the forgiveness of sins.
However, according to the prophecy of the Bible, the truth of life was abolished by Satan. So, the Second Coming Christ must grant us salvation by restoring the Passover of the New Covenant.
To save us in the last age, Christ has already come!
He is very Christ Ahnsahnghong nim who brought us the truth of life, the Passover.
We can receive salvation on the last judgment, only when we believe in Christ Ahnsahnghong nim who comes as the savior a second time.
