Assalamu alaikum - Trying to Understand Why Islam Makes Sense to Me

Assalamu alaikum, I hope you’re doing well. I wanted to share some thoughts and get some guidance because I’ve been reflecting a lot about faith lately. I grew up in a Christian environment, but over time I’ve become disappointed by things I’ve seen. Many people who say they follow Jesus (peace be upon him) don’t always act in ways that reflect his teachings. In a few churches I visited I felt unwelcome and noticed politics and coldness in the community. That has been especially visible where I live in the United States - a lot of moral confusion, an obsession with lust and materialism, and people chasing status while acting like they’re virtuous. Even among those who call themselves Christians I’ve seen hypocrisy and hostility. It feels like humility and deeper values have been replaced by pride and selfishness. Social media makes this worse for me sometimes. On a personal level, I’ve seen people profess Christian values but behave contrary to them, and that’s left me frustrated and confused. It often seems like Jesus is used more as a social symbol than a guide. Lately I’ve been seeing a Muslim sister, and I admire her devotion and values. That has made me curious about Islam. I find the emphasis on God’s oneness and the logic behind it compelling. I’ve always struggled with the idea of Jesus (peace be upon him) being God because it seems to conflict with strict monotheism. I’d appreciate help understanding a few things from a Muslim perspective, since I’m still learning: 1. The story of Prophet Ibrahim (Abraham) rejoicing about the coming of Jesus and recognizing him as the Messiah - how is this understood in Islam? (Christian interpretations sometimes say Abraham called Jesus the son of God; I’m not sure about that and would welcome correction.) 2. How Muslims view the accounts of Jesus’ disciples claiming to see him alive after the crucifixion. 3. Passages where Jesus is reported to call himself divine or the son of God, and the biblical reports of his miracles - how are these understood differently in Islam? 4. The relics and miracles associated with the True Cross - what is the Islamic perspective on such relics and claims? 5. My biggest question: Islam teaches that Jesus was not actually crucified but was raised to heaven and it only appeared that way. That confuses me because Mary (peace be upon her) and others were present and Pontius Pilate ordered the execution. How does Islam explain these reports, and why does it differ from Christian accounts? I’d also like to learn more about how Islam presents historical and spiritual evidence for its truth - for example, the revelation to Prophet Muhammad (peace be upon him) by Angel Jibreel (Gabriel), the Quran’s message, and other signs. Thank you for reading - it means a lot. I’m approaching this with an open heart and mind and would appreciate thoughtful, kind answers. Sorry if I’m unclear in places; I’m just hoping for sincere, in-depth reasoning about why Islam is true. Jazakum Allahu khairan.
