According to the Bible, God will come a second time in the flesh to give us salvation.
So if we don't receive Second Coming Jesus, we can't receive salvation in this last age.

Heb9:28 so Christ was sacrificed once to take aways the sins of many people; and he will appear a second time, not to bear sins, but to bring salvation to those who are waiting for him.

It is clearly that Jeus must come a second time to bring salvation. Then how can we recognize Second Coming Jesus who comes in the flesh like us? Jesus Christ came in the flesh and He established the Passover of the New Covenant(Mt26:17-28).
Through the Passover, God gives us the forgiveness of sins and eternal life. So only God can establish the Passover to give us salvation.

Isa 25:6-9 On this mountain the Lord almighty will prepare a feast of rich food for all peoples, a banquet of aged wine - the best of meats and the finest of wines. ...... he will swallow up death forever. ...... In that day they will say, "Surely this is our God; we trusted in him, and he saved us. This is the Lord, we trusted in him; let us rejoice and be glad in his salvation.

Here, 'he will swallow up death forever' refers to give us eternal life. And 'aged wine' means that the wine didn't use for a long time. In the Bible, God gives us eternal life through the Passover of the New Covenant. So this prophecy indicates that the Passover will keep again.

Jesus Christ established the Passover 2,000 years ago, however, the Passover was abolished by Satan in 325 A.D. at the Council of Nicaea. So for a long time, the Passover didn't keep anymore. But, God will be recovered the Passover.

According to the prophecy of the Bible, Second Coming Jesus Ahnsahnghong came in the flesh and restored the Passover of the New Covenant to give us eternal life. Only Christ Ahnsahnghong recovered the Passover because He is our God.

Let's receive Second Coming Jesus Ahnsahnghong who is our Savior and leads us to the kingdom of heaven.
