Thank you. Learning from everything, Bible, science, and history, is worthy goal for every Christian. Being stuck in the middle ages with all its filth and ignorance is nothing to recommend itself to anyone.
Yes you use and twist the things said in the Bible to teach something entirely different.
Yes Christianity reconciles these passages just fine without any of your dogmas of universalism and reincarnation.
Let us begin by reading the actual text rather than what you dictate it says.
Matthew 5:21-26 21 “You have heard that it was said to the men of old, ‘You shall not kill; and whoever kills shall be liable to judgment.’ 22 But I say to you that every one who is angry with his brother shall be liable to judgment; whoever insults his brother shall be liable to the council, and whoever says, ‘You fool!’ shall be liable to the hell of fire. 23 So if you are offering your gift at the altar, and there remember that your brother has something against you, 24 leave your gift there before the altar and go; first be reconciled to your brother, and then come and offer your gift. 25 Make friends quickly with your accuser, while you are going with him to court, lest your accuser hand you over to the judge, and the judge to the guard, and you be put in prison; 26 truly, I say to you, you will never get out till you have paid the last penny.
Matthew 5:43-48 43 “You have heard that it was said, ‘You shall love your neighbor and hate your enemy.’ 44 But I say to you, Love your enemies and pray for those who persecute you, 45 so that you may be sons of your Father who is in heaven; for he makes his sun rise on the evil and on the good, and sends rain on the just and on the unjust. 46 For if you love those who love you, what reward have you? Do not even the tax collectors do the same? 47 And if you salute only your brethren, what more are you doing than others? Do not even the Gentiles do the same? 48 You, therefore, must be perfect, as your heavenly Father is perfect.
Sins are self-destructive habits which grow like a cancer to destroy our free will and everything of value within us. So we cannot keep anything of them, not even a single one of them.
Luke 15 4 “What man of you, having a hundred sheep, if he has lost one of them, does not leave the ninety-nine in the wilderness, and go after the one which is lost, until he finds it? 5 And when he has found it, he lays it on his shoulders, rejoicing. 6 And when he comes home, he calls together his friends and his neighbors, saying to them, ‘Rejoice with me, for I have found my sheep which was lost.’ 7 Just so, I tell you, there will be more joy in heaven over one sinner who repents than over ninety-nine righteous persons who need no repentance.
As for the prodigal son in Luke 15:11-32, this is a bit long so I shall let people look it up for themselves. Suffice it to say that NOWHERE in this text does it say “Not one will be lost!” It only says “more joy in heaven over one sinner who repents than over ninety-nine righteous persons who need no repentance” and that is all. Indeed the message of Christianity is that it is all about repentance and never about entitlement. Your effort to cut Christianity down to a little cult ruled over by yourself excluding everyone who will not buy into your teaching of universalism has FAILED!
And now with a little context John 3: 14 And as Moses lifted up the serpent in the wilderness, so must the Son of man be lifted up, 15 that whoever believes in him may have eternal life.” 16 For God so loved the world that he gave his only Son, that whoever believes in him should not perish but have eternal life. 17 For God sent the Son into the world, not to condemn the world, but that the world might be saved through him.
I cannot be surprised that the one thing common in modern Christianity that you latch onto are the elements of Gnosticism with its gospel of salvation by knowledge. All the ideological cults love that stuff because they just want to change the content of the required beliefs to those of their own. But the quoted text does not say what you claim. Not even close. The passage is not about requirements for salvation which Jesus addresses in Matthew 19 (which I will put below) quite clearly, but about the motivation for God sending His Son to the world. God does indeed want people to believe in Jesus so that they might be saved, but it is not the intent of the passage to say that a belief in particular teachings is either sufficient or necessary for salvation.
Matthew 19 16 And behold, one came up to him, saying, “Teacher, what good deed must I do, to have eternal life?” 17 And he said to him, “Why do you ask me about what is good? One there is who is good. If you would enter life, keep the commandments.” 18 He said to him, “Which?” And Jesus said, “You shall not kill, You shall not commit adultery, You shall not steal, You shall not bear false witness, 19 Honor your father and mother, and, You shall love your neighbor as yourself.” 20 The young man said to him, “All these I have observed; what do I still lack?” 21 Jesus said to him, “If you would be perfect, go, sell what you possess and give to the poor, and you will have treasure in heaven; and come, follow me.” 22 When the young man heard this he went away sorrowful; for he had great possessions. 23 And Jesus said to his disciples, “Truly, I say to you, it will be hard for a rich man to enter the kingdom of heaven. 24 Again I tell you, it is easier for a camel to go through the eye of a needle than for a rich man to enter the kingdom of God.” 25 When the disciples heard this they were greatly astonished, saying, “Who then can be saved?” 26 But Jesus looked at them and said to them, “With men this is impossible, but with God all things are possible.”
Salvation comes not from what we believe and do but from God.
