We live must make choices and beliefs, because we are created by God and God created humans is to worship Him. Humans but for them to worship God. The only human task is worship, not limited to ritual activities, but all human activities must be intended for worship.

So much, we can't even calculate it. when your Lord declares, actually if you are grateful, God will add (favor) to you.

Our Lord in this life, that promise has been put forward by our spirit since we were still in the womb.
