We do not all believe in one God. The different religions in the world believe in different gods. All of us do not believe in the same God. Bro Eli Soriano explained this to us through this video. We are serving different gods. The gods which the people of other religions are serving is different from the God of the christians which is the God of the Bible.
The differences in the belief patterns of the various religions of the world is because we are serving different gods. Some people do not believe in the Lord Jesus Christ. Others are they who called themselves christians but do not accept the writing of the Apostle Paul. So, every religion has its own peculiarity because of what they believe in.
The true God is the God of the Bible. He is the God who created the entire universe. He is the Father of our Lord Jesus Christ. He is the God who inhabits the heavens. So, if anyone wants to believe in the true God, he should believe in the God of the Bible.
We have only one true God which is the almighty God
