Jesus said we can know the truth. We have to pray for Holy Spirit to help our understanding, read with an open mind, and be willing to let go of any preconceived ideas as we find out that they are not really from the Bible. The Ethiopian Eunich was humble enough to accept help from Philip and the Beroeans were humble enough to listen to Paul and check the scriptures closely to see if what Paul was saying was so as he reasoned with them from the scriptures.
(Acts 17:2) So according to Paul’s custom he went inside to them, and for three sabbaths he reasoned with them from the Scriptures,
(Acts 17:10-11) Immediately by night the brothers sent both Paul and Silas out to Be·roe′a, and these, upon arriving, went into the synagogue of the Jews. 11 Now the latter were more noble-minded than those in Thes·sa·lo·ni′ca, for they received the word with the greatest eagerness of mind, carefully examining the Scriptures daily as to whether these things were so.
(2 Timothy 3:16-17) All Scripture is inspired of God and beneficial for teaching, for reproving, for setting things straight, for disciplining in righteousness, 17 that the man of God may be fully competent, completely equipped for every good work.
(Acts 8:26-40) However, Jehovah’s angel spoke to Philip, saying: “Rise and go to the south to the road that runs down from Jerusalem to Ga′za.” (This is a desert road.) 27 With that he rose and went, and, look! an E·thi·o′pi·an eunuch, a man in power under Can·da′ce queen of the E·thi·o′pi·ans, and who was over all her treasure. He had gone to Jerusalem to worship, 28 but he was returning and was sitting in his chariot and reading aloud the prophet Isaiah. 29 So the spirit said to Philip: “Approach and join yourself to this chariot.” 30 Philip ran alongside and heard him reading aloud Isaiah the prophet, and he said: “Do you actually know what you are reading?” 31 He said: “Really, how could I ever do so, unless someone guided me?” And he entreated Philip to get on and sit down with him. 32 Now the passage of Scripture that he was reading aloud was this: “As a sheep he was brought to the slaughter, and as a lamb that is voiceless before its shearer, so he does not open his mouth. 33 During his humiliation the judgment was taken away from him. Who will tell the details of his generation? Because his life is taken away from the earth.” 34 In answer the eunuch said to Philip: “I beg you, About whom does the prophet say this? About himself or about some other man?” 35 Philip opened his mouth and, starting with this Scripture, he declared to him the good news about Jesus. 36 Now as they were going over the road, they came to a certain body of water, and the eunuch said: “Look! A body of water; what prevents me from getting baptized?” 37 —— 38 With that he commanded the chariot to halt, and they both went down into the water, both Philip and the eunuch; and he baptized him. 39 When they had come up out of the water, Jehovah’s spirit quickly led Philip away, and the eunuch did not see him anymore, for he kept going on his way rejoicing. 40 But Philip was found to be in Ash′dod, and he went through the territory and kept on declaring the good news to all the cities until he got to Caes·a·re′a.
(2 Corinthians 10:3-5) For though we walk in the flesh, we do not wage warfare according to [what we are in the] flesh. 4 For the weapons of our warfare are not fleshly, but powerful by God for overturning strongly entrenched things. 5 For we are overturning reasonings and every lofty thing raised up against the knowledge of God; and we are bringing every thought into captivity to make it obedient to the Christ;
(Nehemiah 8:8) And they continued reading aloud from the book, from the Law of the true God, clearly explaining it and putting meaning into it; so they helped the people to understand what was being read.The Qur'an states that it is a perfect book preserved on tablets in heaven (Surah 85:21-22). If the Qur'an is a perfect book from Allah, then there shouldn't be any contradictions in it. Of course, the Muslims will deny any contradictions exist in the Qur'an, but they do. Some of the contradictions below could be debated, but some of them are clearly contradictions.
A contradiction occurs when one statement on a subject excludes the possibility of another. The first one here is a good example. In Surah 19:67, it states that man was created out of nothing. In 15:26, man is created from clay. Since clay is something, we have a contradiction since "nothing" excludes the possibility of "clay." Both cannot be true.
