There is no active evidence of the god of Islam ~ only the book, but
people have committed heinous crimes against innocent people for
this "god" of the Islamic book, contradicting the law of the true God.
What you suggest is impossible, and in fact, when Jesus returns to
reign as King ~ What will you do? Everyone will know there is only
one God, one faith, and one Mediator between God and man. Jesus.
My Christian faith does not stand on faith alone, but on experiences
of the Holy Spirit, as Christian faith began (examples in book of Acts)
I and many other Christians have our own evidence of the true God.
He has answered specific prayers and for one matter on which I asked
for information ~ He sent a man to my church the very same week with
the answer. The pastor didn't know the guy was visiting .. he introduced
him and invited him to preach - all unplanned - but the very first words he
spoke about the topic he decided on, precisely answered my question.
I have witnessed people being healed in the name of Jesus, by the laying
on of hands. Cancer disappeared - that biopsies had been taken from.
There are gifts of the Spirit some people receive, by which the presence
of God is apparent and active. He remains the same God, having the
same plans and intentions for His people and this world. He made a
COVENANT with us, and it remains in place until Jesus Christ returns.
My God is not schizophrenic ... He didn't give Muhammad new rules.
