You must find who Jesus is for yourself. The word trinity is not in the Bible and nowhere does the Bible exhort us to preach the trinity or to teach that Jesus is God. Once you know who Jesus is, you'll know what to do and what to believe.
The NT Bible message has been simple. For all have sinned and come short of God's glory. The wages of sin is death, but God's gift is eternal life through Jesus Christ our Lord. He is the only way to God. Jesus said, “No one comes to God except through me. You will die in your sin unless you believe I am He.”
Muslims would be foolish to ignore it. They would have to ignore it at their own spiritual peril. Ignoring this message is a spiritual disorder to say the least!!!
Muslims shouldn't tell us people of the Book what to believe about Jesus, because we must all learn who He is for ourselves. That is why Jesus never made a declaration on who He was, but when people realized who He was they worshipped Him and Jesus didn't stop them. So come to your own conclusions
