Guns cannot kill

A person came to know about the Lord while he was living in a remote village. However, the whole village was enraged, including his relatives, who rose against him and expelled him.
Like friends of Daniel: As he departed, his uncle took hold of him. He placed his pistol on his forehead, threatening to kill him if he did not deny Christ. Like Daniel’s friends Shadrach, Meshach, and Abednego, he boldly said, “You cannot kill me, as God is my life.” (Daniel 3:16-28) The uncle pulled the trigger, but nothing happened. Annoyed, he tried again, but it did not fire. Lifting his pistol, pointing toward the sky, she shot, and there was a blast. God delivered him miraculously. The whole village got terrified and asked him to go away.
Sickness: The uncle who tried to kill him had a nose infection after the expulsion of the disciple of the Lord Jesus Christ. He tried many hospitals, but he was not healed. As he was lying on his bed being treated, he saw a vision. As God warned Laban not to harm Jacob, God spoke to him, not to harm his nephew, instead inviting him to pray. (Genesis 31:24) He sent word through his relatives requesting his nephew to come and meet him.
Prayer of the righteous: He was willing to forgive, refused to hold grudges or bitterness, and the new disciple went to meet him. With faith and confidence, he interceded for the uncle. He was miraculously healed. Even the doctor who was treating him was astonished and gave glory to God. After this healing, a few people from his family became followers of Jesus Christ.
Becoming a Pastor: Then, he moved to a large city after that and started the ministry by going door to door, sharing about Christ. He marvellously had many believers and thus planted a church. God has blessed him with a congregation of 150 people in about 5 years. Even amid persecution and hatred everywhere, God used him to fulfil His plan.
Do I understand that the gates of hell cannot prevail against the church?
