In my opinion, there are several verses in/from/of the Bible which are/is powerful and true. But I would share/mention only two verses from the Bible (King James version). Here it is-
“God is not a man, that he should lie; neither the son of man, that he should repent: hath he said, and shall he not do it? or hath he spoken, and shall he not make it good?”-(The Bible 23:19).
And Jesus answered him, The first of all the commandments is, Hear, O Israel; The Lord our God is one Lord.”(The Bible 12:29).
Similar thing mentioned in the Quran also:
“Say: He is Allah, the One and Only (God, Lord and creator), ‘Allah-us-Samad’ (The Self-Sufficient Master, Whom all creatures need, He neither eats nor drinks, He is eternal, He is the one who doesn’t have death or end). He neither begets nor is born, And there is none co-equal or comparable unto Him.”-(The Quran 112).
As a researcher of World Religions, I can say the Quran and the Bible has some similarities in some cases/matters like we can see in/on the above.
