To receive salvation, we should seek savior through the only Bible. It says that we can recognize the savior, the second coming Crist through the secret hidden in the life of king David in the Old Testament.

Hos 3:5 Afterward the Israelites will return and seek the LORD their God and David their king. They will come trembling to the LORD and to his blessings in the last days.

Those who seek David can receive God's blessings. In the last days indicates these days. This is a prophecy to be fulfilled in this age when we are living. It's very important messages for us to meet savior. David we have to meet is a prophetical David who appears to give salvation in the last days. Then who is the prophetical David?

Lk 1:31-32 You will be with child and give birth to a son, and you are to give him the name Jesus. He will be great and will be called the son of the Most High. The Lord God will give him the throne of his father David.

Jesus cane to this earth according to the prophecy if king David. As it's said that Jesus would sit on David throne. We should compare the works of Jesus to those of David.

2 Sa 5:4 David was thirty years old when he became king, and he reigned forty years.

David was anointed at the age of 30 and became a king. He ruled Israel for 40 years. As his life was a prophecy, it was fulfilled by Jesus as the prophetical David. Just like king David, Jesus as the prophetical David was baptized at 30 to fulfill the prophecy of David's throne and had to preach the gospel for 40 years the duration of David's throne.
As you know, Jesus preached it just for three years. All the prophecies in the Bible must be fulfilled, (Mt 5:18). For such reasons, Jesus needs to come to this earth a second time to fulfill the prophecy that competes preaching for 40 years.

Heb 9:28 He will appear a second time, not to bear sin, but to bring salvation to those who are waiting for him.

The second coming Christ to fulfill the prophecy of David must come in the flesh like Jesus.
How to find out who the prophetical David? He brings the sign to recognize for only us.

Isa 55:3 Give ear and come to me; hear me, that your soul may live. I will make an everlasting covenant with you, my faithful love promised to David.

Then the prophetical David must have the sign that is the everlasting covenant.

Heb 13:20 May the God of peace, who through the blood of the eternal covenant brought back from the dead our Lord Jesus, that great Shepherd of the sheep.

Through these words, we can understand the covenant. Jesus established with His blood is the everlasting covenant. It's the New Covenant Passover. Jesus, who came as the prophetical David established the New Covenant Passover and preaching to give salvation 2000years ago.
In the same way, the second coming Christ who saves us and gives salvation has to establish the New Covenant and preach it for 37 years to complete the prophecies. According to the all prophecies in the Bible, It's Christ Ahnsahnghong who is our savior in the last days.
He was born 1918, baptized at 30 years of 1948 and started His Ministry at his age of 30 as prophetical king David. In 1985, the 37th years, he passed away after preaching the gospel, exactly for 37 years. Most of all, he has established the New Covenant Passover with Hid blood to give salvation for us. He is the king David we must seek and fear in the last days,(Hos3:5). Absolutely he is our God the Bible testifies to give salvation to us.
