The Answer to this question is simple. However, first of all, why do Christians beleive in Jesus Christ as the Savior? If the Bible did not exist, even if Christ had come we can't beleive in Him because there was never any written record. However, due to the fact that the Holy Bible testifies about Jesus Christ there are so many Christians that beleive in Him. It's the same way with Christ Ahnsahnghong. We beleive in Him because according to Bible prophecy He is the Root of David. Let's find out the way the disciples recognized Christ 2,000 years ago.
John 6:68 "Simon Peter answered him, "Lord, to whom shall we go? You have the words of eternal life. We believe and know that you are the Holy One of God."
Because Jesus had the words of Eternal Life, this is the reason the Apostles recognized their savior. What words were spoken by Christ?
John 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."
BECAUSE JESUS CHRIST SPOKE OF ETERNAL LIFE THROUGH THE PASSOVER BY GIVING US HIS FLESH AND BLOOD ON THAT DAY (LK 22:133,19-20) THIS IS HOW THE DISCIPLES RECOGNIZED GOD IN THE FLESH.
However, the Passover was abolished in the year 321 AD by Constantine, the establisher of the Roman Catholic Church. Ever since so much paganism entered the church and the truth was destroyed. However God promised to come a Second Time with a New Name (Rev 2:17, Heb 9:28) to give us salvation. That name is CHRIST AHNSAHNGHONG and the Salvation He's brought us is the Passover.
Please pray to God to open your eyes and ears to give you knowledge and recognize Christ Ahnsahnghong who is the same Mighty God that said "Let there be light" and there was light. This is why We beleive in Heavenly Father Christ Ahnsahnghong, because He brought the words of eternal life, the PASSOVER! GOD BLESS YOU!
