Friend @kuoba01 you have hit the nail on the head when you say:

Believing in God must also imply a commitment and a change of life.

People decide what to believe in, the ideal is to respect and have faith in God whatever the religion, respect his commandments.Keep us in that right line and not let the evil that haunts us take over our lives.

It is true, only God has the true power, his benevolence is immense, knows if there is something I fear in this world is his wrath and punishment.
