It is good to live a religious life, so if there were no religion we wouldn't have known what worshipping God would be all about.
Religion is just a place where we have knowledge of the God we serve, the commandments and everything that consigns God our creator. Everything that we have had in the world sometimes might present itself in the way of fake form.
We have that true religion to help us know the one which is true and which one is false. We get to learn about God and all that concerns him, his ways, the truthfulness. The truth is that religion conveys that God is not in that.
That God is above us always, so the two religions accept that the Lord Jesus Christ is the son of God.
Those who are serving the true God are those who will keep escaping the problems of life. So they are those who allow God to judge for all their sinful works on earth. That is why we must always follow this religion and to know which one is true and which one is false.
