The bible we all know that we have only one God which is the true God, the God who created heaven and earth and also gave us life to live. The Bible teaches that not everyone worships or serves Him, even if they use the word "God." People follow different beliefs and religions, and Jesus taught that true worship must be based on truth and a genuine relationship with God. Simply claiming to know God is not enough; our faith and obedience should agree with His revealed Word.
Jesus also said, "I am the way and the truth and the life. No one comes to the Father except through me." (John 14:6).
This shows that, according to the Bible, people do not all serve the same God if they reject the God revealed through Jesus Christ. The holy bible encourages everyone to serve the true God both in truth and in spirit.
