Really interesting

While I'm not here to discuss the points you have raised as I'm on a different journey seeking peace and clarity, you've sparked my curiosity and encouraged me to consider your question from a new perspective.
If Christianity is such a religion of truth, can you tell me why do all Christian countries implement punitive measures, such as imprisoning thieves and killers, when the Bible & Christ himself emphasize forgiveness and repentance rather than such actions? Why do these nations act in ways that contrary to the teachings of their faith?
Let us delve deeper, what if both your question and mine came from human interpretations and complexities surrounding religion, rather than the original messages of the prophets or messengers? this complexity may be an unnecessary aspect found in every religion. Could this concept hold some truth?
if "God" is so powerful, how come He allow his son Christ to be crucified and killed by his enemies? How come He allow His enemies to kill other prophets/messengers? How come He allow the challenges and suffering that many prophets/messengers faced while delivering their messages to their communities?
You know what, the interesting part of your statement about Israel leads me to expect that you are agree with the massacre and Genocide being carried out in Gaza by Israeli occupation. Is my expectation correct?
I don't know why you say that.
Just look back at my posts on this site, you'll see that I've clearly stated I'm seeking answers to gain a better understanding of Christianity. I notice that you and others often pose questions that seem to criticize Islam in bad way, while I have never asked anything that disrespects your religion or Christ. Your unrelated questions compel me to respond, which diverts me from my main purpose/journey here.
There is no such thing as a "Christian" country. Not yet, anyway. When Jesus returns, He will institute His reign which will be perfect in every way.
The percentage of Christians is small in most countries. So governments must regulate accordingly. If there was no crime, there would be no need for laws. God forgives sin, but there are conditions. There is also the principle of sowing and reaping. If a Christian has a brain snap and decides to rob a bank, God will forgive the sin. But the Christian will reap what he has sown from the secular authorities.
God did not just allow Jesus to be killed by His enemies. Jesus volunteered. Jesus said that no one took His life from Him. As we've said before, sin incurs a debt that no one can pay. All mankind is spiritually bankrupt. The wages of sin is death. All people are born dead in trespass and sin. So we have nothing with which to pay the debt.
Jesus was the only sinless man. So He had the right to pay for the sin of the world. Muslims, so I understand, believe the Old Testament. Read Isaiah 53 and you will see God's plan of salvation centuries before it came to pass.
Jesus sacrificed His life so that sinners might live. That includes you and me.
I reject your claim that Israel is committing genocide or massacres. Tell me what army warns civilians of impending attacks? Has Hamas warn Israeli citizens they were about to be attacked? Around 75% of Gaza's buildings have been destroyed. There are still around 2 million Gazans. Israel is destroying Hamas tunnels and Hamas firing points. Hamas chooses to build tunnels under civilian infrastructure. It's not surprising if a building collapses when the tunnels is destroyed.
The only groups threatening genocide are Israel's enemies. They are predominately Muslim. That's just the way it is, not an anti Muslim slur. Muslims danced in the streets on the 7th of October. Have you watched the footage recorded by Hamas terrorists? Did you hear the recording of the Hamas fighter who range his family to boast that he had killed Jewish parents and their children? You do know what "from the river to the sea" means, I'm sure.
I suggest that you look up the definitions of "massacre" and "genocide". 2 million Israeli Arabs live in peace in Israel, apart from being attacked by Israel's enemies from time to time. There is no genocide, no massacre and no apartheid.
Christianity is not a national thing, unlike Islam. Many Western nations base their criminal codes on the Bible. That is changing as those nations increasingly turn from God. Islam is a theocracy. That has is not the case in America, for example, even if it is a supposedly Christian nation. The constitution requires separation of church and state.
Jesus warned His followers that the world would hate us. The world, especially the religious, hated Him first. To understand God's dealings with Israel requires us to know the terms of the covenant God made with Israel. That's a huge subject. I'm happy to discuss that, but it's too extensive for this forum. If you wish, I will give you my email address and we can discuss the issue that way.
I do not hate anyone. I wish that all men would be saved and come to the knowledge of the truth. My life has not been easy. Being a Christian does not mean exemption from life's trials. However, Jesus is my Lord, my Saviour and my Friend. He has been with me at my lowest points in life. As the Bible says, "many are the afflictions of the righteous, but the Lord delivers him out of them all." Does Mohamed come to your aid when life gets too much? Do you have peace even in life's trials and tribulations? I do. You could too. Accept Jesus as your Lord and Saviour.
