The Koran as stated above does Testify of Christ as does the Baha’i writings as follows;
Baha’u’llah, Abdul’Baha and Shoghi Effendi have all written about Jesus the Christ. All confess to Jesus and His revelation - From Baha’u’llah **“Know thou that when the Son of Man yielded up His breath to God, the whole of Creation wept with a great weeping. By sacrificing Himself, however, a fresh capacity was infused into all created things. Its evidences, as witnessed in all the peoples of the earth, are now manifest before thee. The deepest wisdom which the sages have uttered, the profoundest learning which any mind hath unfolded, the arts which the ablest hands have produced, the influence exerted by the most potent of rulers, are but manifestations of the quickening power released by His transcendent, His all-pervasive, and resplendent spirit . . . He it is who purified the world. Blessed the man who, with a face beaming with light, hath turned towards Him”. **(Baha’u’llah Gleanings 86)
“It is also recorded in the Gospel according to St. Luke, that on a certain day Jesus passed by a Jew who was sick of the palsy, and lay upon a couch. When the Jew saw Him, he recognized Him, and cried out for His help. Jesus said unto him: “Arise from thy bed; thy sins are forgiven thee.” Certain of the Jews, standing by, protested saying: “Who can forgive sins, but God alone?” And immediately He perceived their thoughts, Jesus answering said unto them: “Whether is it easier to say to the sick of the palsy, arise, and take up thy bed, and walk; or to say, thy sins are forgiven thee? that ye may know that the Son of Man hath power on earth to forgive sins.”
This is the real sovereignty, and such is the power of God’s chosen Ones! All these things which We have repeatedly mentioned, and the details which We have cited from divers sources, have no other purpose but to enable thee to grasp the meaning of the allusions in the utterances of the chosen Ones of God, lest certain of these utterances cause thy feet to falter and thy heart to be dismayed”. - Baha’u’llah (‘The Book of Certitude’)
The last passage also requires One to Overcome and see the Message within the Messenger as Jesus said "We are from God, and whoever knows God listens to us; but whoever is not from God does not listen to us:. That is one must Listen to Christ, One must Listen to Muhammad, One must listen to the Bab and Baha’u’llah, Otherwise we listen from what is of this world and until we listen to them we will not see the “Spirit of Truth”.
The connection from the Bible to the Koran and then Baha’i Writings do need to be studied. May we all Love Jesus the Christ with all our heart and all Soul
