religion is a formula, ceremonially based, customs and forms - etc.
we as beings created by God and made in the image of God the Father, Son and Holy Spirit (let us make man in our image Genesis 1:26)
we are created to worship - go anywhere and you can find "man" worshiping, something, .... we are created by God to worship and praise Him -
So as a relationship with Jesus Christ is Christianity - to the Christian the World calls it 'religion' in some cases but the two are vastly different.
At any rate, man - due to how he has been created, is curious and has questions and the drawing that many feel is an inbuilt desire to seek God, but when left unattended or trained improperly; man seeks 'religion' and it's trinkets, prayers, performances, ceremonies, formulas and so on -
why is it that we are drawn to religious questions?
God really wants us to know Him and to seek Him -----
