What’s wrong in believing in God’s existence?

I really do not understand why Education Secretary Armin Luistro had to give in to demands of a group of people who wanted the words “maka-Diyos” (pro-God) and “God-loving” removed from the Department of Education’s (DepEd) mission and vision statements.

The group, calling itself Free Thinkers,” claimed that not everyone in this country believes in God or is a member of a religion or sect, thus these words should be stricken out from the statements of a government institution.
