The difference is in Jesus Christ

I love that you believe in God, that you believe in His son's death and resurrection and that you believe in the gift of the Holy Spirit. Keep up the faith. Your comment was that Christianity and even the Bible has loopholes and that Christianity is like every other religion which promotes peace and love.
Our God is a perfect God, His words are truth(John 17:17). In Isaiah 7:10-17 God promised us His Son, John 3:16 tells us the purpose of His coming. John 3:31-36 tells us the position of His Son, Jesus Christ, Luke 24:46-47 tells us that Jesus suffered, died and rose that repentance and remission of sins should be preached in His Name to all nations, beginning at Jerusalem, salvation is for all. Jesus Christ was the Word, the world was made through Him, and He came to His own(the world) but they did not receive Him. But as many received Him, to them He gave right to become children of God, to those who believe in His name (John1:1,10-12).
Salvation my brother, is for all. Eternal life is for those who by patient continuance in doing good seek for glory, honor and immortality. Glory, honor and peace to everyone who works what is good, to the Jew first and also to the Greek(Romans 2:7,10). Therefore by the deeds of the law no flesh will be justified in His sight, for by the law is the knowledge of sin. But now the righteousness of God apart from the law is revealed, being witnessed by the Law and the Prophets, even the righteousness of God, through faith in Jesus Christ, to all and on all who believe. For there is no difference; for all have sinned and fall short of the glory of God, being justified freely by His grace through the redemption that is in Christ Jesus, Whom God set forth as a propitiation by His blood, through faith, to demonstrate His righteousness, because in His forbearance God had passed over the sins that were previously committed, to demonstrate at the present time His righteousness, that He might be just and the justifier of the one who has faith in Jesus(Romans 3:20-26). Jesus commissioned his disciples to "Go therefore and make disciples of all nations" (Matthew 28:19a). "Go into all the world and preach the gospel to every creature. He who believes and is baptized will be saved; but he who does not believe will be condemned."(Mark 16:16).
My brother as a believer, Peter had already spoken that we should be mindful of the words which were spoken before by the holy prophets, and of the commandment of them, the apostles of the Lord and Saviour, knowing that scoffers will come in the last days, walking according to their own lusts, saying "where is the promise of His coming? For since the fathers fell asleep, all things continue as they were from the beginning of creation." For this they willfully forget: that by the word of God the heavens were of old, and the earth standing out of water, by which the world that then existed perished, being flooded with water. But the heavens and the earth which now exist are kept in store by the same word, reserved for fire until the day of judgement and perdition of ungodly men(2Peter 3:2-7). Beloved, do not believe every spirit, but test the spirits, whether they are of God; because many false prophets have gone out into the world. By this you know the Spirit of God:every spirit that confesses that Jesus Christ has come in the flesh of God, and every spirit that does not confess that Jesus Christ has come in the flesh is not of God. And this is the spirit of the Antichrist, which you have heard was coming, and is now already in the world. You are of God, little children, and have overcome them, because He who is in you is greater that he who is in the world. They are of the world. Therefore they speak as of the world, and the world, and the world hears them. We are of God. He who knows God hears us. By this we know the spirit of truth and the spirit of error(1John 4:1-6).

I pray God that this message achieves it's purpose in Jesus's Name Amen.
