There is only one truth. It cannot be that Muslim is true and Christian is also true at the same time. If one is true, therefore the other is false. If Allah is true this means Jesus Christ is false. If Jesus is true, therefore it is impossible for Allah to be true.
For you to discern which of the two is true God or religion. You should ask yourself who between Jesus and Allah can give you hope? salvation? eternity? Who between the two can answer your prayer? Can give you peace? Can light your life? Can supply your needs? Can give you protection everyday? Who between the two can share your burden? Can allow you to suffer trial, persecution, sickness, but will give you victory at the end? who between the two is patience with your sins, will not easily anger? Who between the two is not selfish? Who between the two that if you anchor your life to Him can put a new song in your life? Lastly, who between the two have died for you?
If you answer Allah or Jesus to these questions, it should be your personal decision.
I hope and pray that you will choose JESUS to be your God.
God bless you!
